System Management Software

Embedded management software includes the RAIDar web-browser interface (WBI) and the command-line interface (CLI) described below.

RAIDar

RAIDar is the primary interface for configuring and managing the system. A web server resides in each controller module. RAIDar enabl es you to manage the system from a web browser that is properly configured and that can access a control ler module through an Ethernet connection.
Information about using RAIDar is in its online help and in the Administrator’s Guide.

Command-Line Interface

The embedded CLI enables you to configure and manage the system using individual commands or command scripts through an out-of-band RS-232 or Ethernet connection.
Information about using the CLI is in the CLI Reference Manual.

Obtaining IP Values for Your Storage System

Before installing or configuring your system, obtain IP and gateway addresses for the Ethernet management ports on your R/Evolution storage system from your network administrator.
A different IP address should be assigned for each Ethernet management port (one each for controller A and controller B).
You will use these values when you set IP addresses for Ethernet management ports during initial configuration (see “Setting Management Port IP Addresses Using the CLI” on page 56).
Note – You can also obtain IP values for Ethernet management ports from a DHCP
server if one is available. For more information, refer to the Administrator ’s Guide.

6. Use from four to eight #8-32 x 3/16-inch flathead screws on each side to attach the side brackets to each side of the encl osure. The right and left side brackets are identical.
Note – To allow adjustment of the brackets, do not tighten the screws completely
until the enclosure is mounted in the rack.
a. Use the ali gnment marks (Figure 2-2) stamped into the side brackets to position
the brackets and screws. The alignment marks show depth in inches. Determine the depth you require and align the rear-most alignment mark on the
side bracket with the rear-most threaded holes on the enclosure. Make sure that the alignment mark corresponding to the depth you want lines up with both the top and bottom holes.
Figure 2-2 Side Bracket With Alignment Marks
b. On one side, insert the first two screws through the side bracket slots above and
below the alignment mark into the rear-most threaded holes in the enclosure. For example, to mount the enclosure in a 27-inch deep rack, position the side
bracket so that the 27-inch alignment mark is aligned with the rear-most threaded holes in the enclosure.
c. Insert up to six more screws throug h the side bracket slots into the other threaded
holes in the side of the enclosure.
d. Repeat Step b and Step c to attach the other side bracket to the enclosure.
7. Attach the rear brackets to the rear vertical posts of the rack. Use two screws and two washers, if required, to attach each bracket to a post.
Use the appropriate fasteners for the posts; either:
Four #10-32 x 1/2-inch or 1-inch panhead screws with #10 washers
Four 5-mm panhead screws with #10 washers
Four 6-mm panhead screws (no washers required)
8. If necessary, remove the drive modules and power and cooling modules from the enclosure to reduce the weight.

9. Lift the enclosure and slide the side brackets into the rear brackets, which are attached to the rear posts.
Adjust the depth of the side brackets so that the slots nearest the ends of the side brackets align with the four PEM nuts in the rear brackets.
10. Attach each side bracket to a rear bracket. Use from four to six #8-32 x 1/4-inch panhead screws to attach each side brack et to
a rear bracket.
11. Make sure that the enclosure is le vel and then secure the mounting ears on the front of the enclosure to the rack face. Use two screws for each ear.
Use the appropriate screws for the rack; either:
Four #10-32 x 1/2-inch panhead screws
Four #10-32 x 1-inch panhead screws
Four 5-mm panhead screws
Four 6-mm socket cap screws
12. Ti ghten the screws in the side brackets.
13. If you removed modules from the enclosure, reinsert them.
14. If you attached the optional front support brackets to the rack face, remove those brackets.
Reattach the ear caps using gentle pressure.

Connecting Controller and Drive Enclosures

Note – For additional recommendations on connecting controller and drive
enclosures, see the Best Practices Guide.
Use the supplied SAS cables to connect a controller enclosure to up to four drive enclosures. Figure 2-4 and Figure 2-5 show the recommended fault-tolerant cabling patterns. In an enclosure, the upper module is designated A and the lower module is designated B.
When connecting multiple drive enclosures, use reverse cabling to ensure the highest level of fault tolerance. For example, Figure 2-5 shows controller A connected to drive module 1A, and the chain of connections continuing down. Controller B is connected to the lower module (B) of the last drive enclosure in the chain, with connections moving in the opposite direction.
Fault-tolerant cabling is recommended b ecause it enables the controllers to access remaining drive enclosures if any one drive enclosure fails. However, the system also supports non-fault-tolerant cabling using the supplied SAS cables.
Figure 2-6 shows non-fault-tolerant cabling between a controller and up to four drive enclosures.
Note – For clarity, the schematic illustrations of the controllers shown in this
section show only relevant details such as expansion ports. For detailed illustrations showing all components, see “Hardware Components and LEDs” on page 11.

DC Ground Cable Connections

DC-powered versions of the 5730 and 5130 have a pair of ground studs on the right rail bracket to which the ground cable connects. The other end of the ground cable connects to the cabinet grounding rail. In addition, there is a ground cable in the unterminated end of DC input power cable that connects from the power supply to the fuse panel or breaker panel. The ground cable in this cable must also connect to the cabinet grounding rail.

DC Wiring and DC Power Requirements

The system is suitable for installation as part of the Common Bonding Network (CBN).
The system’s Battery Return (BR) Input Terminals are considered to be an Isolated DC Return (DC-I).The following are requ ired for all installations:
All DC 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 of your power source matches the voltage 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 ± 5 percen t fluctuation. The customer facilities must also provide su itable surge protection.
Site wiring must include an earth ground connection to the DC 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 preven t possible damage to the DC power distribution boxes and other components in the rack, use an external, independent power source that is isolated from large switching loads.

DC Power System Warnings

To reduce the risk of electric shock or damage to the equipment DC power supplies must be installed in accordance with the following guidelines:

Testing the Enclosure Connections

Use this procedure to power on the newly installed system.
1. Press the power switches at the back of each drive enclosure to the On ( This ensures that the disks in the drive enclosures have enough time to completely
spin up before being scanned by the RAID modules in the controller enclosure. Depending on your configuration, it can take several minutes for the system to power up.
While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no LEDs on the front and back of the enclosure are yellow, the po wer-on sequence is complete and no faults have b een detected.
For a description of LED behavior and status, see “Hardware Components and LEDs” on page 11.
2. Press the power switches at the back of the controller enclosure to the On position. If the enclosure’s power-on sequence succeeds as described in Step 1, the system is
ready to use.

Correcting Enclosure IDs

When installing a system with drive enclosures attached, the enclos ure 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 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 RAIDar or the CLI. This will reorder the enclosures, but can take up to two minutes for the enclosure IDs to be corrected.

For additional recommendations on connecting controller enclosures to data hosts, refer to the Best Practices Guide.

Host System Requirements

Data hosts connected to R/Evolution 2730 FC Controller Enclosures must meet the following requirements:
To configure an FC HBA that is directly attached to controller enclosure host
ports, set the HBA parameters as specified in your storage system’s Release Notes. This ensures the HBA can ident ify the system.
Data host operating systems must support multipathing. For information on
installing the R/Evolution MPIO DSM, refer to Installing the R/Evolution 2730 MPIO DSM on Microsoft Windows Server 2003 availabl e at the following

1. In a web browser, go to Enclosure Services (SES) driver package,
r-evo-ses-version.zip, to a location that the data host can access.
2. Extract the package contents to a temporary folder on the host.
3. In that folder, double-click
4. Click Finish. The driver is installed.
5. Optionally, delete the extracted files and the SES driver package.
crc.dothill.com and download the R/Evolution SCSI
Setup.exe to install the driver.

Configuration Considerations

Before connecting the controller enclosure to one o r more data hosts, consider the following options and limitations. Fault tolerance and performance requirements determine whether to optimize your configuration for high availability or high performance.

Using a Direct or Switch Attach Configuration

Attaching the controller enclosure directly to data hosts i s suitable for environments where the storage is only used by one or two hosts.
Switch attach storage places one or more FC switches between the controller enclosure and data hosts. This enables more than one host to share a storage system and provides a level of redundancy if more than one switch is used.
44 R/Evolution 2730 Getting Started Guide • January 2009
Page 45

Using Host Port Interconnects

When the internal connections between host ports are enabled through RAIDar, host port 0 on each controller is internally connected to host port 1 on the other controller. This provides redundancy in the event one controller fails (failover) by making volumes owned by the failed controller accessible on the surviving controller.
Enable port interconnects when controller enclosures are attached directly to hosts and high availability is required, or when switch ports are at a premium and faul t tolerance is required but highest performance is not.
When ports are not interconnected, volumes owned by a controller are ac cessible from two of its host ports only. Use this default setting when controller enclo sures are attached through one or more switches, or when they are attached directly but performance is more important than availability.

Using Loop or Point-to-Point Topology

R/Evolution 2730 FC Controller Enclosures use Fibre Channel Arbitrated Loop (loop) topology by default.
Using loop topology enables hosts to see all volumes on all ports after failover. Use loop topology, where possible, as it provides the most flexible and host­independent, fault-tolerant configuration. Point-to-point topology restricts the ability for the system to present volumes from both controllers after a fai lover, limiting the overall configuration choices.
When ports are interconnected, you can use loop topology only. When ports are not interconnected, you can use either loop or point-to-point topology.
Note – Point-to-point topology is supported for switch attach configurations only.
For additional guidelines on connecting controller enclosures to hosts, refer to the Best Practices Guide. For information on placing and connecting enclosures safely, refer to the Site Planning Guide. For information on how controllers present volumes to data hosts, see the Administrator's Guide.
Chapter 3 Connecting Hosts 45
Page 46

Connecting Direct Attach Configurations

This section explains how to connect the controller enclosure directly to data hosts. It shows configurations that support high availability and high performance, and notes when host port interconnects must be enabled.
The controller enclosure has four host connection s, two per controller. Connect FC cables from host ports on each controller to FC HBAs on data hosts, as shown in the following figures. To maintain redundancy, connect each data host to both controller A and controller B.
Caution – Fiber optic cables are fragile. Do not bend, twist, fold, pinch, or step on
the fiber optic cables. Doing so can degrade performance or render data unavailable.
Note – For clarity, the schematic illustrations of the controllers shown in this
section show only relevant details such as host ports. For detailed illustra tions showing all components, see “Hardware Components and LEDs” on page 11.

Connecting Switch Attach Configurations

This section explains how to connect the controller enclosure to data hosts through one or more external FC switch.
The controller enclosure has four host connections, two per controll er. Connect FC cables from controller hosts ports to switch ports, and from switch ports to data hosts, as shown in the following figures.
To maintain redundancy, connect each data host through the switch or switches to both controller A and controller B. Make sure that link speed and topology settings on switches match those on the controller host ports to which they are connected. A speed mismatch prevents the host from accessing the storage system.
Caution – Fiber optic cables are fragile. Do not bend, twist, fold, pinch, or step on
the fiber optic cables. Doing so can degrade performance or cause data loss.
Note – For clarity, the schematic illustrations of the controllers shown in this

Setting Management Port IP Addresses Using the CLI

Ethernet Management 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 Ethernet management port on each controller module.
Once new IP addresses are set, you can change them as needed using RAIDar.
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.
Note – The Site Planning Guide provides installation and configuration worksheets
that you can use to record values. You can download this guide at the following location:

Configuring Host Ports

Note – If you need to change FC Loop ID settings as described below, consult with
your network administrator on the best addresses to use.
To config ure controller enclosure host ports:
1. Select Manage > General Config > Host Port Configuration.
2. In the Controller Module Host Port Configuration panels, for each port to which an HBA or switch is attached, set the appropriate link speed.
An FC port’s link speed must match the speed of the FC HBA or switch to which the port is connected. In a dual-controller system, if FC port interconnects are enabled, changing the speed of a port on one controller also change s the speed of the interconnected port on the other controller.
3. Click Update Host Port Configuration.
4. In the Advanced Options panel, configure FC loop ID, port interconnect, and topology settings as required for your configuration:
FC Loop ID: (Loop topology configurations only) If you want data hosts to
identify a controller using a specific address, click Change FC Loop ID. In the Requested Loop ID for Host Ports panel, select a specific number (from 1 to 125) for each controller, click Save and Continue, and then click OK to restart the controller.
During loop initialization the controller will request the specified ID but it might be assigned another ID instead.
Port Interconnect Settings: (Direct attach configurations only) If your
configuration requires that host port interconnects be enabled, click Change FC Port Interconnect Settings. In the Host Port Configuration panel, set Internal Host Port Interconnect to Interconnected (enabled), and click Save and Continue.
This setting affects all FC ports on both controllers.
Note – If one or more ports are set to use point-to-point topology, you cannot
enable interconnects.
Fibre Channel Topology: (Switch attach configurations only) To change the
topology used on controller FC ports from Loop to Point to Point, click Change Host Port Topology. In the Controller Module Host Port Configuration panels, select Point to Point for each port, and click Save and Continue.

Note – If interconnects are enabled, you cannot use point-to-point topology.
The Host Port Configuration page displays again.

Creating Virtual Disks

Two or more disk drives can be logically combined to form a virtual disk. The combined storage capacity can then be partitioned into volumes. RAIDar provides both manual and automatic methods for creating virtual disks, as described in its online help and in the Administrator ’s Guide.
As an example, the following steps use the manual method to create two virtual disks with the following characteristics:
RAID 5, in which parity is distributed across all disk drives in the virtual disk
Five disk drives per virtual disk
One spare disk drive dedicated to each virtual disk
One volume per virtual disk, where the volume is not visible to data hosts
To create both virtual disks:
1. Select Manage > Virtual Disk Config > Create A Vdisk.
2. Select Manual Virtual Disk Creation (Detail-based).
3. Type a name for the virtual disk. The name is case-sensitive and can i nclude 17 characters. Allowed charact ers
include letters, numbers, hyphens, underscores, and spaces.
4. Select RAID 5 – Parity RAID, Parity Distributed.
5. Click Create New Virtual Disk.
6. Select five drives of the same size and type (all SAS or all SATA).
7. For the dedicated spare drive option, select Yes and click Continue.
8. Select a drive to be the spare and click Continue.
9. For the number of volumes, select 1. Notice that by default the volume will not be exposed to (accessible by) hosts.
10. Click Create Virtual Disk. A page is displayed that shows the progress of initializi ng the virtual disk.
62 R/Evolution 2730 Getting Started Guide • January 2009
Page 63
11. Click the li nk to create another virtual disk.
12. Repeat Step 2 to Step 10 to cr eate a second virtual disk with a different name.

Mapping a Data Host to a Volume

To enab le a data host to access a volume you created, you must map the volume to the host. The port World Wide Name (WWN) of each host connected to the system is automatically added to the system’s global host port list.
Before mapping a data host to a volume you must identify the data host’s port WWN and a LUN that the host is not using.
To map a data host to a volume:
1. Select Manage > Volume Management > Volume Mapping > Map Hosts To Volume. Notice that your first virtual disk and its volume are selected, and the volume’s host
mapping values are set to None.
2. In the Assign Host Access Privileges panel: a. Select the host port WWN value that you identified before beginning. b. Type the LUN that you identified.
Notice that the mapped host will have read-write access through all controller host ports.
c. Click Map It.
Chapter 4 Configuring a System for the First Time 63

Testing the Configuration

To determine that yo ur system is ready for use, test the configuration as follows:
1. In RAIDar, select Monitor > Vdisk Status and view the configuration information for each virtual disk.
The virtual disk status is Critical during initi alizatio n but you ca n perform I/ O to the volume.
2. From the data host: a. Make the volume an operating system partition. b. Verify that you can access the mapped volume and the volume size shown o n the
data host matches the size shown in RAIDar. c. Verify that you can write data to the volume. If the above tests succeed, your system is ready for use.
3. Once you have determined that your system is ready for use, tighten the thumb screws on all SAS cables.
4. Optionally, unmount the volume and delete the test vdisks.

Logging Out of RAIDar

If you do not log out of RAIDar when you have finished using it, other manage users cannot log in to the same controller module and your IP address stays logged in for 30 minutes (the default auto-logout timeout setting).
To log out of RAIDar:
1. Click Log Off at the bottom of the menu. The Log Off page is displayed.
2. Click Log Off.

Next Steps

You have completed the initial configuration tasks covered in this guide. For additional information on configuring your system and performing administrativ e tasks, refer to RAIDar’s online help or the Administrator’s Guide. If you encounter problems with the operation of your system, refer to the Troubleshooting Guide.

APPENDIX
A

Powering the System Off and On

This appendix describes how to power off and power on the system when needed.

Powering Off the System

The system rarely needs to be powered off. You remove power only when you plan to physically move the system to another location.
Use this procedure when you need to power off the system.
1. Stop all I/O from hosts to the system.
2. Use RAIDar to shut down both controllers. Wait until RAIDar indicates that processing is complete.
3. Press the power switches at the back of the controller enclosure to the Off position.
4. Press the power switches at the back of each expansion enclosure to the Off position.

Powering On the System

Power on any expansion enclosures before powering on the controller enclosure. This ensures that the disks in the expansion enclosures have enough time to completely spin up before being scanned by the RAID controllers in the controller enclosure. Depending on your configuration, it can take several minutes for the system to power up.
Use this procedure to turn power on for all enclosures installed in a rack.
1. Press the power switches at the back of each expansion enclosure to the On ( position.
While enclosures power up, their LEDs blink. After the LEDs stop blinking, if no LEDs on the front and back of the enclosure are yellow, the po wer-on sequence is complete and no faults have b een detected.

2. Press the power switches at the back of the controller enclosure to the On (–) position.
If the enclosure’s power-on sequence succeeds as described in Step 1, the system is ready to use.
