Drivers And Firmware

Storage Management is tested with the supported controller firmware and drivers. In order to function

properly, the controller must have the minimum required version of the firmware and drivers installed.

The most current versions can be obtained from the support site.

NOTE: You can verify which firmware and drivers are installed by selecting the Storage object in the

tree view and clicking Information/Configuration. You can also check the Alert Log for alerts

relating to unsupported firmware and driver versions.

It is also recommended to obtain and apply the latest server system BIOS on a periodic basis to benefit

from the most recent improvements. For more information on server system BIOS, see the system

documentation.

Isolate Hardware Problems

If you receive a timeout alert related to a hardware device or if you otherwise suspect that a device

attached to the system is experiencing a failure, then to confirm the problem:

• Verify that the cables are correctly connected.

• If the cables are correctly connected and you are still experiencing the problem, then disconnect the

device cables and reboot the system. If the system reboots successfully, then one of the devices may

be defective. For more information on hardware, refer to the hardware device documentation.

Rescan To Update Information On SCSI Controllers

On SCSI controllers, use the Rescan controller task to update information for the controller and attached

devices. This operation may take a few minutes if there are a number of devices attached to the

controller.

If the Rescan does not properly update the disk information, you may need to reboot your system.

Replacing A Failed Disk

You may need to replace a failed disk in the following situations:

• Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk

• Replacing A Failed Physical Disk That Is Part Of A Non-Redundant Virtual Disk

Replacing A Failed Disk That Is Part Of A Redundant Virtual Disk

If the failed disk is part of a redundant virtual disk, then the disk failure will not result in data loss. You

must replace the failed disk immediately, however, as additional disk failures can cause data loss.

If the redundant virtual disk has a hot spare assigned to it, then the data from the failed disk is rebuilt onto

the hot spare. After the rebuild, the former hot spare functions as a regular physical disk and the virtual

disk is left without a hot spare. In this case, you must replace the failed disk and assign the replacement

disk as a hot spare.

NOTE: If the redundant virtual disk does not have a hot spare assigned to it, then replace the failed

disk using the procedure described in Replacing a Physical Disk Receiving SMART Alerts.
