the system.

Drivers And Firmware
Storage Management is tested with the supported controller rmware and drivers. In order to function properly, the controller must have
the minimum required version of the rmware and drivers installed. The most current versions can be obtained from the support site.
NOTE: You can verify which rmware and drivers are installed by selecting the Storage object in the tree view and clicking
Information/Conguration. You can also check the Alert Log for alerts relating to unsupported rmware and driver versions.
It is also recommended to obtain and apply the latest server system BIOS on a periodic basis to benet 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 conrm 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.

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.
