Cache

To enable faster data access from disk storage, the following two types of caching are performed:

• Posted-write caching. The controller writes user data in the cache memory on the module rather than

directly to the drives. Later, when the storage system is either idle or aging — and continuing to receive new I/O data — the controller writes the data to the drive array.

• Read-ahead caching. The controller detects sequential array access, reads ahead into the next

sequence of data, and stores the data in the read-ahead cache. Then, if the next read access is for cached data, the controller immediately loads the data into the system memory, avoiding the latency of a disk access.

Transportable CompactFlash

During a power loss or array controller failure, data stored in cache are saved off to non-volatile memory (CompactFlash). These data are then written to disk after the issue is corrected. To protect against writing incomplete data to disk, the image stored on the CompactFlash is verified before committing to disk.

4 Service port (used by service personnel only) 5 SAS Out port (connects to another drive enclosure) 6 Optional I/O module

In single-controller configurations, if the controller has failed or does not start, and the Cache Status LED is on or blinking, the CompactFlash will need to be transported to a replacement controller to recover data not flushed to disk. (See Controller failure in a single-controller configuration on page 52 for more information.)

HP 2000i G2 Modular Smart Array User Guide 19

CAUTION: To preserve the existing data stored in the CompactFlash, you must transport the

CompactfFlash from the failed controller to the replacement controller using a procedure outlined in the HP StorageWorks 2312i/2324i G2 controller replacement instructions, shipped with the replacement

controller. Failure to use this procedure will result in the loss of data stored in the cache module. The CompactFlash must stay with the same enclosure. If the CompactFlash is used/installed in a different enclosure, data loss/data corruption will occur.

IMPORTANT: In dual controller configurations, there is no need to transport a failed controller’s cache to

a replacement controller because the cache is duplicated between the controllers.

Super-capacitor pack

To protect RAID controller cache in case of power failure, the 2312i G2 and 2324i G2 are equipped with super-capacitor technology, in conjunction with CompactFlash memory, built into each controller module to provide unlimited cache memory backup time. The super-capacitor pack and CompactFlash memory in each controller module provide unlimited cache memory backup time. The super-capacitor pack provides energy for backing up unwritten data in the write cache to the CompactFlash in the event of a power failure. Unwritten data in CompactFlash memory is automatically committed to disk media when power is restored. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second on and 9/10 second off.

Connecting controller and drive enclosures

Connecting controller and MSA2000 3.5" 12-drive enclosures

You can connect up to four MSA2000 3.5" 12-drive enclosures to a 2312i G2 and up to three MSA2000

3.5" 12-drive enclosures to a 2324i G2. The cabling diagrams shown in this section show the recommended fault-tolerant cabling patterns. Connecting an MSA2000 3.5" 12-drive enclosure to a 2312i G2 or 2324i G2 requires mini-SAS to SAS cables.

IMPORTANT: Adding a fourth drive enclosure to a 2312i G2 may require a separate, longer cable. For a

current list of supported cables, check the MSA2000 G2 QuickSpecs located on the HP MSA products page at http://www.hp.com/go/msa QuickSpecs link is located on the right.

When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault tolerance. Controllers and I/O (expansion) modules are identified by <enclosure-ID><controller-ID>. For example, Figure 3 on page 24 shows controller 1A connected to I/O module 2A, and the chain of connections continuing down. Controller 1B is connected to the lower module (B) of the last drive enclosure in the chain, with connections moving in the opposite direction.

Connecting controller and MSA70 2.5” 25-drive enclosures

The 2324i G2 can also be attached to an MSA70 running firmware version 2.18 or later. For information about the MSA70, including detailed steps to upgrade the firmware, see the HP StorageWorks 70 Modular Smart Array Enclosure User Guide located on the MSA2000 Software Support/Documentation CD shipped with your product, or at http://hp.com/support/manuals

. Select MSA SAN Arrays, and then select your product. The

Connecting controller and mixed-connect 3.5” and 2.5” drive enclosures

You can connect LFF MSA2000 3.5" 12-drive enclosures and SFF MSA70 2.5” 25-drive enclosures to a 2324i G2 controller enclosure in mixed-connect fashion, as shown in Figure 6 on page 26, and as further described in the following documents:

• HP StorageWorks MSA2000 G2 Installation Instructions

• HP StorageWorks 2000 G2 Modular Smart Array Cable Configuration Guide

These documents also address connection of the controller enclosure to either LFF or SFF drive enclosures. A few sample connection diagrams are provided in Figures 1-5 on the following pages.

Additional cable requirements for drive enclosures

IMPORTANT:

• When installing SAS cables, only use supported SAS 4x cables with 3Gb connectors.

• SAS to SAS 0.6m cables are provided for the MSA2000 3.5" 12-drive enclosure (one per controller).

• Mini-SAS to mini-SAS 0.5m cables are provided with the MSA70 drive enclosure (one per controller).

• The maximum cable length allowed in any configuration is 2m.

• If additional or longer cables are required, they must be ordered separately (see MSA2000 G2 Quick

Specs).

Testing enclosure connections

1. Press the power switches at the back of each drive enclosure to On.

IMPORTANT: This ensures that the disks in the enclosures have enough time to completely spin up before

being scanned by the RAID modules in the controller enclosure.

While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no LEDs on the front and back of the enclosure are amber, the power-on sequence is complete and no faults have been detected.

For a description of LED behavior and status, see LED descriptions on page 35.

2. Press the power switches at the back of the controller enclosure to On.

Depending on the number and type of drives in the system, it can take several minutes for the system to power up.

If the enclosure’s power-on sequence succeeds as described in Step 1, the system is ready to be connected to hosts.

26 Installing the enclosures

Obtaining IP values

NOTE: For help with configuring your MSA2000 G2 product, also see the MSA2000 Software

Support/Documentation CD shipped with your product.

Setting management port IP addresses using DHCP

1. Look in the DHCP server’s pool of leased addresses for two IP addresses assigned to “HP

StorageWorks MSA Storage.”

2. Use the MSA Device Discovery Tool to discover “HP StorageWorks MSA2300i” storage devices on the

local LAN through SNMP. If the MSA Device Discovery tool is not installed on your system, then install the program:

a. Insert the MSA2000 Software Support/Documentation CD into the computer’s CD drive. b. When the dialog appears onscreen, double-click AUTORUN.exe. c. From the dialog’s Tools tab, select MSA Device Discovery Tool. d. Complete the installation.

3. Use a ping broadcast to try to identify the device through the host’s ARP table.

If you do not have a DHCP server, you will need to ask your system administrator to allocate two IP addresses and set them using the CLI during initial configuration (see Setting management port IP

addresses using the CLI).

Setting management port IP addresses using the CLI

If you did not use the DHCP to set network port IP values, set them manually (default method) as described below.

Network ports on controller module A and controller module B are configured with the following default values:

• Management Port IP Address: 10.0.0.2 (controller A), 10.0.0.3 (controller B)

• IP Subnet Mask: 255.255.255.0

• Gateway IP Address: 10.0.0.1

If the default IP addresses are not compatible with your network, you must set an IP address for each management port using the command-line interface (CLI) embedded in each controller module. The CLI enables you to access the system using RS-232 communication and terminal emulation software.

Use the CLI commands described in the steps below to set the IP address for the Network port on each controller module.

Once new IP addresses are set, you can change them as needed using SMU. Be sure to change the IP address via SMU before changing the network configuration.

NOTE: Changing IP settings can cause management hosts to lose access to the storage system.

1. From your network administrator, obtain an IP address, subnet mask, and gateway address for

controller A and controller B.

HP 2000i G2 Modular Smart Array User Guide 27

2. Use the provided micro-DB9 serial cable to connect controller A to a serial port on a host computer.

4 Connecting hosts

Host system requirements

Data hosts connected to 2312i G2 and 2324i G2 arrays must meet the following requirements:

• Depending on your system configuration, data host operating systems may require that multi-pathing is

supported.

TIP: See the HP StorageWorks MSA2000 Family VDS and VSS Hardware Providers Installation

Guide and HP StorageWorks MSA2000 Family MPIO DSM Installation Guide to aid in planning

and implementing your MPIO DSM installation.

If fault tolerance is required, then multi-pathing software may be required. Host-based multi-path software should be used in any configuration where two logical paths between the host and any storage volume may exist at the same time. This would include most configurations where there are multiple connections to the host or multiple connections between a switch and the storage.

• Use 2000sa G2 Modular Smart Array MPIO DSM with Windows Server 2003. To obtain the

2000sa G2 Modular Smart Array MPIO DSM, go to the HP MSA products page at

http://www.hp.com/go/msa

products.

• Use native Microsoft MPIO DSM support with Windows Server 2008. Use either the Server

Manager or the command line interface (mpclaim CLI tool) to perform the installation. Refer to the following web sites for information about using the Windows 2008 native MPIO DSM:

http://support.microsoft.com/gp/assistsupport http://technet.microsoft.com (search the site for “multipath I/O overview”)

• Use the HP Multi-path Device Mapper for Linux Software with Linux servers. To download the appropriate device mapper multi-path enablement kit for your specific enterprise Linux operating system, go to http://www.hp.com/go/devicemapper

• To prevent Microsoft Windows 2003 data hosts from displaying the Found New Hardware Wizard

Connecting the enclosure to data hosts

Cable connections vary depending on configuration. Common cable configurations are shown in this section. A complete list of supported configurations resides on the MSA2000 G2 product site at

http://hp.com/support/manuals

Guide, which is updated to describe newly-supported direct connect, switch-connect, and expansion configuration options for the MSA2000 G2.

Any number or combination of LUNs can be shared among connected servers, provided the total does not exceed 512 LUNs per MSA2000 G2. Moreover, a volume cannot be mapped to LUN zero.

iSCSI host ports

2312i Modular Smart Array and 2324i Modular Smart Array use Internet SCSI (Small Computer System Interface) interface protocol for host port connection, featuring either one or two controller modules. Each controller provides two iSCSI host ports — supporting data rates up to 1Gb/second, featuring a 1.8 GHz processor with128 MB memory, and 1 GB cache — using either one-way or mutual CHAP (Challenge-Handshake Authentication Protocol).

Connecting remote management hosts

The management host directly manages systems out-of-band over an Ethernet network.

1. Connect an Ethernet cable to the network port on each controller.

2. Connect the other end of each Ethernet cable to a network that your management host can access

(preferably on the same subnet).

NOTE: Connections to this device must be made with shielded cables with metallic RFI/EMI connector

hoods in order to maintain compliance with FCC Rules and Regulations.

32 Connecting hosts

5 Basic operation

Powering on/powering off

Before powering on the enclosure for the first time:

• Install all disk drives in the enclosure so the controller can identify and configure them at power-up.

• Connect the cables and power cords to the enclosure as explained in the installation poster.

• Generally when powering up, make sure to power up the enclosures and associated data host in the

following order:

•Drive enclosures first

• Controller enclosure next

• Data hosts last (if they are powered down for maintenance purposes)

TIP: Generally, when powering off, you will reverse the order of steps used for powering on.

To power on the system:

1. Press the power switches at the back of each drive enclosure to the On position.

2. Press the power switches at the back of the controller enclosure to the On position.

To power off the system:

1. Stop all I/O from hosts to the system.

Ensure that the host has flushed all I/O from cache to disk before the controller is shut down.

2. Use SMU to shut down both controllers. See the SMU online help for information on shutting down a

controller. Wait until SMU indicates that processing is complete.

3. Press the power switches at the back of each drive enclosure to the Off position.

4. Press the power switches at the back of the controller enclosure to the Off position.

Updating firmware

After installing the hardware and powering up the enclosure for the first time, verify that the controller and all enclosures have the latest firmware. SMU enables you to view the firmware and hardware version information for each enclosure.

TIP: See Signing in to SMU on page 41 for SMU usage.

To view controller module firmware versions, in the Configuration View panel, right-click the system, select View > Overview, and select the Versions component in the System Overview Table.

To view expansion module firmware versions, in the Configuration View panel, right-click a drive enclosure and select View > Overview. Expansion module A’s firmware version is shown as EMP A Revision; expansion module B’s firmware version is shown as EMP B Revision.

For software and firmware updates, including update instructions, go to http://www.hp.com/go/msa Select MSA SAN Arrays, select your product, and go to Support.

Selecting an appropriate time to perform the online upgrade

To ensure the success of an online upgrade, selecting the appropriate time is essential. Selecting a period of low I/O activity will ensure the upgrade completes as quickly as possible, and will avoid disruptions to host and applications due to timeouts. Attempting to upgrade a storage system that is in the middle of processing a large I/O intensive batch job will likely cause hosts to lose connectivity with the storage system. Consequently, finding an appropriate time for the upgrade is very important.

LED Description Definition

10 Cache Status Green — Cache is dirty (contains unwritten data) and operation is

normal. The unwritten information can be log or debug data that remains in the cache, so a Green cache status LED does not, by itself, indicate that any user data is at risk or that any action is necessary. Off — In a working controller, cache is clean (contains no unwritten data). Blinking green — A CompactFlash flush or cache self-refresh is in progress. Indicates cache activity (See also If the controller has

failed or does not start, is the Cache Status LED on/blinking? on page 52).

If the LED is blinking evenly, a cache flush is in progress. When a controller module loses power and write cache is dirty (contains data that has not been written to disk), the super-capacitor pack provides backup power to flush (copy) data from write cache to CompactFlash memory. When cache flush is complete, the cache transitions into self-refresh mode.

If the LED is blinking momentarily slowly, the cache is in a self-refresh mode. In self-refresh mode, if primary power is restored before the backup power is depleted (3–30 minutes, depending on various factors), the system boots, finds data preserved in cache, and writes it to disk. This means the system can be operational within 30 seconds, and before the typical host I/O time-out of 60 seconds, at which point system failure would cause host-application failure. If primary power is restored after the backup power is depleted, the system boots and restores data to cache from CompactFlash, which can take about 90 seconds.

The cache flush and self-refresh mechanism is an important data protection feature; essentially four copies of user data are preserved: one in each controller’s cache and one in each controller’s CompactFlash.

11 Host Activity Off — Host ports have no I/O activity.

Blinking green — At least one host port has I/O activity.

12 Expansion Port Status Off — The port is empty or the link is down.

Green — The port is connected and the link is up.

NOTE: Once a Link Status LED is lit, it remains so, even if the controller is shutdown via SMU or CLI.

When a controller is shutdown or otherwise rendered inactive —its Link Status LED remains illuminated—falsely indicating that the controller can communicate with the host. Though a link exists between the host and the chip on the controller, the controller is not communicating with the chip. To reset the LED, the controller must be properly power-cycled (see Powering on/powering off on page 33).

Changing the system date and time

You can change the storage system's date and time, which are displayed in the System Status panel. It is important to set the date and time so that entries in system logs and event-notification email messages have correct time stamps.

You can set the date and time manually or configure the system to use Network Time Protocol (NTP) to obtain them from a network-attached server. When NTP is enabled, and if an NTP server is available, the system time and date can be obtained from the NTP server. This allows multiple storage devices, hosts, log files, and so forth to be synchronized. If NTP is enabled, but no NTP server is present, the date and time are maintained as if NTP was not enabled.

NTP server time is provided in Universal Time (UT), which provides several options:

• If you want to synchronize the times and logs between storage devices installed in multiple time zones,

set all the storage devices to use UT.

• If you want to use the local time for a storage device, set its time zone offset.

• If a time server can provide local time rather than UT, configure the storage devices to use that time

server, with no further time adjustment.

Whether NTP is enabled or disabled, the storage system does not automatically make time adjustments, such as for U.S. daylight savings time. You must make such adjustments manually.

To use manual date and time settings

1. In the Configuration View panel, right-click the system and select Configuration > System Settings >

Date, Time. The date and time options appear.

2. Set the options:

• Time. Enter the time in the format hh:mm:ss.

•Month.

•Day.

• Year. Enter the year using four digits.

•NTP. Select Disabled.

3. Click Apply.

42 Configuring a system for the first time

• Disks to include in the vdisk. The table specifies the minimum and maximum number of disks to select.

You can also assign spare disks to automatically replace any disks that fail.

• Number and size of storage volumes to create in the vdisk. By default, the new vdisk will have one

volume. You can change the number of volumes, and optionally change the default size and base name for the volumes. To postpone creating volumes, you can change the number of volumes to zero.

• Control access to the volumes by mapping them to hosts, or masking them from hosts.

Testing the configuration

To determine that the initial configuration is complete, verify host access to a volume:

1. In the Configuration View pane, right-click the vdisk and select View > Overview.

2. From the data host:

a. Create a file system on the volume. b. Verify that you can access the mapped volume and the volume size shown on the data host matches

the size shown in SMU.

c. Verify that you can write data to the volume.

If the above tests succeed, initial configuration is complete. You can proceed with configuring and provisioning the system for daily use.

3. Optionally, unmount the test volume and delete the test vdisk.

Signing out of SMU

If you end a SMU session without signing out, the session automatically ends when the user’s automatic sign-out time expires. If the preference is set to Never, the session ends after 9999 minutes.

1. Click Sign Out in the upper right-hand corner.

8Troubleshooting

Fault isolation methodology

The 2000sa G2 Modular Smart Array storage system provides many ways to isolate faults within the system. This section presents the basic methodology used to locate faults and the associated FRUs (Field Replaceable Units).

The basic fault isolation steps are:

• Gather fault information, including using system LEDs

• Determine where in the system the fault is occurring

• Review event logs

• If required, isolate the fault to a data path component or configuration

Gather fault information

When a fault occurs, it is important to gather as much information as possible. Doing so will help you determine the correct action needed to remedy the fault.

Begin by reviewing the reported fault. Is the fault related to an internal data path or an external data path? Is the fault related to a hardware component such as a drive module, controller module, or power supply? By isolating the fault to one of the components within the storage system, you will be able to determine the necessary action more rapidly.

Determine where the fault is occurring

Once you have an understanding of the reported fault, review the enclosure LEDs. The enclosure LEDs are designed to alert users of any system faults, and might be what alerted the user to a fault in the first place.

When a fault occurs, the Fault ID status LED on an enclosure’s right ear (see Front panel components on page 17) illuminates. Check the LEDs on the back of the enclosure to narrow the fault to a FRU, connection, or both. The LEDs also help you identify the location of a FRU reporting a fault.

Use SMU to verify any faults found while viewing the LEDs. SMU is also a good tool to use in determining where the fault is occurring if the LEDs cannot be viewed due to the location of the system. SMU provides you with a visual representation of the system and where the fault is occurring. It can also provide more detailed information about FRUs, data, and faults.

Review the event logs

The event logs record all system events. It is very important to review the logs, not only to identify the fault, but also to search for events that might have caused the fault to occur. For example, a host could lose connectivity to a virtual disk if a user changes channel settings without taking the storage resources assigned to it into consideration. In addition, the type of fault can help you isolate the problem to hardware or software.

Isolate the fault

Occasionally it might become necessary to isolate a fault. This is particularly true with data paths, due to the number of components comprising the data path. For example, if a host-side data error occurs, it could be caused by any of the components in the data path: controller module, cable, or data host.

If the enclosure does not initialize

It may take up to two minutes for the enclosures to initialize. If the enclosure does not initialize:

• Perform a rescan.

• Power cycle the system.

• Make sure the power cord is properly connected, and check the power source that it is connected to.

• Check the event log for errors.

HP 2000i G2 Modular Smart Array User Guide 47

Correcting enclosure IDs

When installing a system with drive enclosures attached, the enclosure IDs might not agree with the physical cabling order. This is because the controller might have been previously attached to some of the same enclosures during factory testing and it attempts to preserve the previous enclosure IDs if possible. To correct this condition, make sure that both controllers are up, and perform a rescan using SMU or the CLI. This will reorder the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.

To perform a rescan using the CLI, type the following command:

rescan

To rescan using SMU:

1. Verify that both controllers are operating normally.

2. In the Configuration View panel, right-click the system and select Tools > Rescan Disk Channels.

3. Click Rescan.

Controller failure in a single-controller configuration

Cache memory is flushed to CompactFlash in the case of a controller failure or power loss. During the write to CompactFlash process only the components needed to write the cache to the CompactFlash are powered by the super-capacitor. This process typically takes 60 seconds per 1 Gbyte of cache. After the cache is copied to CompactFlash, the remaining power left in the super-capacitor is used to refresh the cache memory. While the cache is being maintained by the super-capacitor, the Cache Status LED flashes at a rate of 1/10 second off and 9/10 second on.

IMPORTANT: Transportable cache only applies to single-controller configurations. In dual controller

configurations, there is no need to transport a failed controller’s cache to a replacement controller because the cache is duplicated between the controllers.

If the controller has failed or does not start, is the Cache Status LED on/blinking?

Answer Actions

No, the Cache LED status is off, and the controller doesn’t boot.

No, the Cache Status LED is off, and the controller boots.

Yes, at a strobe 1:10 rate - 1 Hz, and the controller doesn’t boot.

Yes, at a strobe 1:10 rate - 1 Hz, and the controller boots.

Yes, at a blink 1:1 rate - 1 Hz, and the controller doesn’t boot.

Yes, at a blink 1:1 rate - 1 Hz, and the controller boots.

Transporting Cache

To preserve the existing data stored in the CompactFlash, you must transport the CompactFlash from the failed controller to a replacement controller using a procedure outlined in the HP StorageWorks 2312i/2324i G2 controller replacement instructions, shipped with the replacement controller. Failure to use this procedure will result in the loss of data stored in the cache module.

CAUTION: Remove the controller only after the copy process is complete, which is indicated by the

Cache Status LED being off.

If valid data is thought to be in Flash, see Transporting

Cache; otherwise, replace the controller.

The system is flushing data to disks. If the problem persists, replace the controller.

52 Troubleshooting

Isolating a host-side connection fault

During normal operation, when a controller module host port is connected to a data host, the port’s host link status LED and host link activity LED are green. If there is I/O activity, the host activity LED blinks green. If data hosts are having trouble accessing the storage system, and you cannot locate a specific fault or cannot access the event logs, use the following procedure. This procedure requires scheduled downtime.

IMPORTANT: Do not perform more than one step at a time. Changing more than one variable at a time

can complicate the troubleshooting process.

1. Halt all I/O to the storage system.

2. Check the host activity LED.

If there is activity, halt all applications that access the storage system.

3. Reseat the cable and inspect for damage.

Is the host link status LED on?

This step isolates the problem to the external data path (host cable and host-side devices) or to the controller module port.

Is the host link status LED on?

• Yes – You now know that the host cable, and host-side devices are functioning properly. Return the

cable to the original port. If the link status LED remains off, you have isolated the fault to the controller module’s port. Replace the controller module.

• No – Proceed to the next step.

5. Verify that the switch, if any, is operating properly. If possible, test with another port.

6. Verify that the HBA is fully seated, and that the PCI slot is powered on and operational.

7. Replace the HBA with a known good HBA, or move the host side cable to a known good HBA.

Is the host link status LED on?

• Yes – You have isolated the fault to the HBA. Replace the HBA.

• No – It is likely that the controller module needs to be replaced.

8. Move the cable back to its original port.

Is the host link status LED on?

• No – The controller module’s port has failed. Replace the controller module.

• Yes – Monitor the connection for a period of time. It may be an intermittent problem, which can

occur with damaged cables and HBAs.

5. Move the expansion cable back to the original port on the controller enclosure.

6. Move the expansion cable on the drive enclosure to a known good expansion port on the drive

enclosure. Is the expansion port status LED on?

• Yes – You have isolated the problem to the drive enclosure’s port. Replace the expansion module.

• No – Proceed to Step 7.

7. Replace the cable with a known good cable, ensuring the cable is attached to the original ports used

by the previous cable. Is the host link status LED on?

• Yes – Replace the original cable. The fault has been isolated.

• No – It is likely that the controller module needs to be replaced.

Resolving voltage and temperature warnings

1. Check that all of the fans are working by making sure each power supply’s DC Voltage/Fan

Fault/Service Required LED is off or by using SMU to check for yellow yield icon hardware warnings. (In the Configuration View panel, right click the enclosure and click View > Overview.)

2. Make sure that all modules are fully seated in their slots and that their latches are locked.

3. Make sure that no slots are left open for more than two minutes.

If you need to replace a module, leave the old module in place until you have the replacement or use a blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the enclosure to overheat.

4. Try replacing each power supply one at a time.

5. Replace the controller modules one at a time.

54 Troubleshooting

Sensor locations

The storage system monitors conditions at different points within each enclosure to alert you to problems. Power, cooling fan, temperature, and voltage sensors are located at key points in the enclosure. In each controller module and expansion module, the enclosure management processor (EMP) monitors the status of these sensors to perform SCSI enclosure services (SES) functions.

The following sections describe each element and its sensors.

Power supply sensors

Each enclosure has two fully redundant power supplies with load-sharing capabilities. The power supply sensors described in the following table monitor the voltage, current, temperature, and fans in each power supply. If the power supply sensors report a voltage that is under or over the threshold, check the input voltage.

Table 7 Power supply sensors

Description Event/Fault ID LED condition

Power supply 1 Voltage, current, temperature, or fan fault

Power supply 2 Voltage, current, temperature, or fan fault

Cooling fan sensors

Each power supply includes two fans. The normal range for fan speed is 4000 to 6000 RPM. When a fan’s speed drops below 4000 RPM, the EMP considers it a failure and posts an alarm in the storage system’s event log. The following table lists the description, location, and alarm condition for each fan. If the fan speed remains under the 4000 RPM threshold, the internal enclosure temperature may continue to rise. Replace the power supply reporting the fault.

Table 8 Cooling fan sensor descriptions

Description Location Event/Fault ID LED condition

Fan 1 Power supply 1 < 4000 RPM Fan 2 Power supply 1 < 40 00 RP M Fan 3 Power supply 2 < 40 00 RP M Fan 4 Power supply 2 < 40 00 RP M

During a shutdown, the cooling fans do not shut off. This allows the enclosure to continue cooling.

Temperature sensors

Extreme high and low temperatures can cause significant damage if they go unnoticed. Each controller module has six temperature sensors. Of these, if the CPU or FPGA temperature reaches a shutdown value, the controller module is automatically shut down. Each power supply has one temperature sensor.

When a temperature fault is reported, it must be remedied as quickly as possible to avoid system damage. This can be done by warming or cooling the installation location.

A Environmental requirements and specifications

Safety requirements

Install the system in accordance with the local safety codes and regulations at the facility site. Follow all cautions and instructions marked on the equipment.

Site requirements and guidelines

The following sections provide requirements and guidelines that you must address when preparing your site for the installation.

When selecting an installation site for the system, choose a location not subject to excessive heat, direct sunlight, dust, or chemical exposure. These conditions greatly reduce the system’s longevity and might void your warranty.

Site wiring and AC power requirements

The following are required for all installations using AC power supplies:

• All AC mains and supply conductors to power distribution boxes for the rack-mounted system must be

enclosed in a metal conduit or raceway when specified by local, national, or other applicable government codes and regulations.

• Ensure that the voltage and frequency of your power source match the voltage and frequency inscribed

on the equipment’s electrical rating label.

• To ensure redundancy, provide two separate power sources for the enclosures. These power sources

must be independent of each other, and each must be controlled by a separate circuit breaker at the power distribution point.

• The system requires voltages within minimum fluctuation. The customer-supplied facilities’ voltage must

maintain a voltage with not more than suitable surge protection.

• Site wiring must include an earth ground connection to the AC power source. The supply conductors

and power distribution boxes (or equivalent metal enclosure) must be grounded at both ends.

• Power circuits and associated circuit breakers must provide sufficient power and overload protection. To

prevent possible damage to the AC power distribution boxes and other components in the rack, use an external, independent power source that is isolated from large switching loads (such as air conditioning motors, elevator motors, and factory loads).

• Power circuits and associated circuit breakers must provide sufficient power and overload protection.

HP 2000i G2 Modular Smart Array User Guide 57

Weight and placement guidelines

Refer to Physical requirements on page 59 for detailed size and weight specifications.

• The weight of an enclosure depends on the number and type of modules installed.

• Ideally, use two people to lift an enclosure. However, one person can safely lift an enclosure if its

weight is reduced by removing the power and cooling modules and drive modules.

• Do not place enclosures in a vertical position. Always install and operate the enclosures in a horizontal

orientation.

• When installing enclosures in a rack, make sure that any surfaces over which you might move the rack

can support the weight. To prevent accidents when moving equipment, especially on sloped loading docks and up ramps to raised floors, ensure you have a sufficient number of helpers. Remove obstacles such as cables and other objects from the floor.

• To prevent the rack from tipping and to minimize personnel injury in the event of a seismic occurrence,

securely anchor the rack to a wall or other rigid structure that is attached to both the floor and to the ceiling of the room.

Electrical guidelines

• These enclosures work with single-phase power systems having an earth ground connection. To reduce

the risk of electric shock, do not plug an enclosure into any other type of power system. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

• Enclosures are shipped with a grounding-type (three-wire) power cord. To reduce the risk of electric

shock, always plug the cord into a grounded power outlet.

• Do not use household extension cords with the enclosures. Not all power cords have the same current

ratings. Household extension cords do not have overload protection and are not meant for use with computer systems.

Ventilation requirements

Refer to Environmental requirements on page 59 for detailed environmental requirements.

• Do not block or cover ventilation openings at the front and rear of an enclosure. Never place an

enclosure near a radiator or heating vent. Failure to follow these guidelines can cause overheating and affect the reliability and warranty of your enclosure.

• Leave a minimum of 6 inches (15 cm) at the front and back of each enclosure to ensure adequate

airflow for cooling. No cooling clearance is required on the sides, top, or bottom of enclosures.

• Leave enough space in front and in back of an enclosure to allow access to enclosure components for

servicing. Removing a component requires a clearance of at least 15 inches (37 cm) in front of and behind the enclosure.

Cabling requirements

• Keep power and interface cables clear of foot traffic. Route cables in locations that protect the cables

from damage.

• Route interface cables away from motors and other sources of magnetic or radio frequency

interference.

• Stay within the cable length limitations.

Management host requirements

A local management host with at least one serial port connection is recommended for the initial installation and configuration of a controller enclosure. After you configure one or both of the controller modules with an Internet Protocol (IP) address, you then use a remote management host on an Ethernet network to configure, manage, and monitor.

58 Environmental requirements and specifications

NOTE: Connections to this device must be made with shielded cables with metallic RFI/EMI connector

hoods in order to maintain compliance with FCC Rules and Regulations.

Physical requirements

The floor space at the installation site must be strong enough to support the combined weight of the rack, controller enclosures, expansion enclosures, and any additional equipment. The site also requires sufficient space for installation, operation, and servicing the enclosures, and also requires sufficient ventilation to allow a free flow of air to all enclosures.

Table 12 and Table 13 list enclosure dimensions and weights. Weights are based on an enclosure having

Electrical requirements

Site wiring and power requirements

Each enclosure has two power and cooling modules for redundancy. If full redundancy is required, use a separate power source for each module. The AC power supply unit in each power and cooling module is auto-ranging and is automatically configured to an input voltage range from 88–264 VAC with an input frequency of 47–63 Hz. The power and cooling modules meet standard voltage requirements for both U.S. and international operation. The power and cooling modules use standard industrial wiring with line-to-neutral or line-to-line power connections.

Power cord requirements

Each enclosure is shipped with two AC power cords that are appropriate for use in a typical outlet in the destination country. Each power cord connects one of the power and cooling modules to an independent, external power source. To ensure power redundancy, connect the two power cords to two separate circuits; for example, to one commercial circuit and one uninterruptible power source (UPS).

B Electrostatic discharge

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground card to a grounded workstation or computer chassis. Wrist

straps are flexible straps with a minimum of 1 megohm ± 10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps or boot straps at standing workstations. Wear the straps on both feet when

standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.

Electrostatic discharge

To prevent damage to the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

Preventing electrostatic damage

To prevent electrostatic damage, observe the following precautions:

• Avoid hand contact by transporting and storing products in static-safe containers.

HP 2000i G2 Modular Smart Array User Guide 67

• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.

• Place parts on a grounded surface before removing them from their containers.

• Avoid touching pins, leads, or circuitry.

• Always be properly grounded when touching a static-sensitive component or assembly (see “Grounding

methods” on page 68).

Grounding methods

There are several methods for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist

straps are flexible straps with a minimum of 1 megohm (±10 percent) resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.

• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when

standing on conductive floors or dissipating floor mats.

• Use conductive field service tools.

• Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an HP authorized reseller install the part.

NOTE: For more information on static electricity, or assistance with product installation, contact your HP

authorized reseller.
