G. Set iSCSI Initiator on Windows

iSCSI is an Internet Protocol-based storage networking standard for linking data storage facilities. By carrying SCSI commands over IP networks, iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances. iSCSI can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval. The protocol allows clients (called initiators) to send SCSI commands to SCSI storage devices (targets) on remote servers.

RAID systems use iSCSI Initiator to enable connection of a host computer to an external iSCSI storage array using Ethernet network interface cards.

The following steps are required for enabling iSCSI Initiator:

1. Complete the hardware and software setup of RAID systems.

2. iSCSI Initiator comes pre-installed in Windows 2008 servers. If you are using Windows 2003 server or below, you need to download and install the iSCSI Initiator package to the host computer.

3. Reboot the host computer.

4. Launch iSCSI Initiator.

iSCSI Initiator Configuration:

1. Open iSCSI Initiator.

Note

In Windows 2008 server, click Start > Administrative Tools > iSCSI Initiator to open the application.

The mode of launching the application may vary depending on your server’s operating system.

Accusys A16R/A16U-IS

Accusys A16R/A16U-IS

H. Set PathGuard on Windows 2003 Server

PathGuard is the bundled multi-path IO solution for Windows 2003, 2003 R2 32bit / 64bit, platforms, and it is based on Microsoft Multipath I/O (MPIO) framework. PathGuard consists of MPIO drivers and a web-based path manager GUI that allows you to manage MPIO configurations for multiple host computers.

The MPIO drivers include standard drivers from Microsoft and DSM (Device Specific Module) provided by the RAID system supplier.

The following steps are required for enabling PathGuard MPIO:

1. Complete the hardware and software setup at RAID systems.

2. Install the PathGuard package to the host computer. Register the vendor name and model name of your RAID system to the PathGuard (optional).

3. Install the PathGuard MPIO driver.

4. Reboot the host computer.

5. Launch PathGuard GUI to set multi-path policies.

Windows MPIO framework requires rebooting the host computer when enabling the MPIO driver on the host computer, such that the regular disk device drivers will be replaced by the MPIO disk drivers.

Windows can properly detect multi-path disks only during MPIO driver installation, so reconfiguration (like adding/removing paths or LUNs) requires you to reinstall the PathGuard MPIO driver and reboot the host computer.

You might need also to manually rescan the physical drives (use Computer Management > Storage > Disk Management) When multi-path disks are not properly detected.

Accusys A16R/A16U-IS

To Install PathGuard and MPIO Driver:

1. To install the PathGuard and MPIO Driver, double click the installation file on a host computer (choose the 32-bit or 64-bit installation file according to your host system).

2. Follow the on-screen instructions to start the installation. PathGuard and the MPIO Driver will be installed automatically.

3. Reboot the host computer, and you have completed the installation.

Check the MPIO disk status on the host computer

After the PathGuard and the MPIO Driver has been installed, you can find the new multi-path disk device(s) and the Multi-Path Support displayed in the following screen: Computer Management > Device Manager. (Right-click the My Computer icon on the desktop > select Manage)

Accusys A16R/A16U-IS

1. Go to Computer Management > Device Manager > Disk Drivers and SCSI and RAID controllers to check for the Multi-Path Disk Device and

Multi-Path Support. The following illustration shows a successful installation with Multi-Path Disk Device and Multi-Path Support found in the Device Manager.

2. Make sure the two installed disk devices are in the Disk Management as shown in the illustration. After that, you may format the new disk devices and start using them.

Troubleshooting

General Guidelines

When you encounter issues, the most essential troubleshooting is to check the event log of your RAID system. In addition, you may need to check the system log of the operating system at your host computers.

Because there are a wide variety of hardware and software combinations, use the following checklist for problem determination:

• Check all cables to make sure they are connected properly.

• Check all hardware units are powered on and working properly.

• Check any recent changes in hardware, software, or configurations.

• Verify that the latest version of firmware and software are used.

• Verify that the latest version of BIOS and device driver of HBA are used.

• Verify that the operating systems, HBAs, switches, transceivers, and

hard disks are in the compatibility list.

• Check how to reproduce the problems.

Before you call support, please collect the related information above to assist the support staff in identifying the problems. It is also required to acquire the following three log files:

(1) RAID system user-level event log in human-readable form (.csv or .txt).

(2) RAID system diagnostic-level event log (.bin).

(3) the log file at operating system.

Beeper

When the Beeper Control is set to On, the system will turn on the beeper alarm if one of the following occurs. If the user mutes the beeper via LCD, or GUI, the system temporarily mutes the beeper until a new failure or error occurs.

• Voltage failure or error.

• Power supply failure or error.

• Fan failure or error.

• Temperature failure or error.

• BBM failure or error (when BBM is connected).

• Disk SMART warning.

• Disk bad block over threshold warning.

• Disk group with degraded logical disk and no disk for rebuilding.

• Disk group with faulty logical disks.

• UPS failure or error.

• Controller failure or removed.

• Dual controllers fail to boot up because of configuration conflict.

• Controller failback cannot proceed.

Solutions

See the table below for the solutions for the most common problems.

Problem Cause Solution

Accusys A16R/A16U-IS

Hard disks cannot be recognized by the RAID controller.

Hard disks are offline unexpected.

Exceptional hard disks behaviors.

If a hard disk cannot be ready within a specific period of time during the initialization, the RAID controller will force the hard disks enter faulty state and you cannot see any model information of hard disks.

Internal component failure or reserved space for metadata (RAID configurations) can not be written.

Hardware is not setup properly.

To ensure hard disks have enough time for power-on, you may extend the delay time when boot-up of the RAID controller.

1. Use SMART check or DST (Device Self-Test) to test the hard disks in question.

2. Check the number of bad blocks and warning events reported by the RAID controller.

Adjust hard disk settings such as:

• Extend Disk I/O Timeout to accommodate slow disk operation.

• Increase Disk I/O Retry Time to try I/O more times before giving up.

• Reduce Transfer Speed to mitigate bad signal quality of disks.

• Disable I/O Queue to avoid problematic NCQ support of disks.

• Disable Disk Standby Mode to avoid problematic sleep support of disks.

• Extend Disk Access Delay Time to allow longer time for disk spin-up.

Accusys A16R/A16U-IS

Multiple hard disks are taken offline at a time.

The Web GUI can not be connected.

The replacement controller stops bootup with LCD messages.

Could be system-level problem. For example, if the hard disks in a JBOD system are offline unexpected, poor cabling in SAS or SAS expansion chain would also lead to unexpected hard disk offline. In addition, poor heat ventilation, unstable power supply, or hardware quality issues could also lead to offline of multiple hard disks.

The management network interface is not configured properly.

Configuration conflict discovered by the system. The beeper alerts, and the LCD shows the following messages: (A) CONTR MOD UNEQ: the two controllers are of different model. (B) DB UNEQ: the two controllers have different daughter board. (C) PLD VERS UNEQ: the two controllers have different PLD version. (D) MEM SZ UNEQ: the two controllers install memory of different size. (E) BBM INSTL UNEQ: one controller has BBM, while the other has no BBM. (F) DISK NR UNEQ: The detected disk numbers are not same of both controller.

(G) EXPAN NR UNEQ WILL BE RE-TEST: The detected expan-

sion numbers are not same of both controller.

Use array recovery utility to the RAID configurations. See the User’s manual for more details.

Check if the LED indicators of the Ethernet port are lit up properly (refer to the hardware manual for details), and the IP address has to be set to enable the network interface. You can manually set the IP address by the LCD, or use a DHCP server on the network.

(A/B/C/F) Contact your RAID system supplier to get the correct controller. (D/E) Install proper memory module and BBM. For (H) and (I), press the ENT button on the LCD to update the boot code and firmware code, respectively, and the replacement controller will reboot. For (J) and (K), press the ENT button to overwrite the BBM and enclosure serial number, and the replacement controller will continue bootup. For(L), if disply EXPAN NR UNEQ WILL BE RETEST, please check connection is properly between expansions and controllers. Wait boot agent to retest. For(M), Please first plug-out and return back controller try again. If still have any problem please contact supplier get an help.

Accusys A16R/A16U-IS

The replacement controller stops bootup with LCD messages.

Hard disk shows Unknown state.

Disk group enters degraded mode.
