Replacing Internal Disks

To replace your system's internal disks, refer to the "Hard Drives" and

"Replacing a Hard-Drive Carrier" sections of your system's Hardware Owner's

Manual.

storage enclosure's Hardware Owner's Manual.

Recovering After a Disk Failure

This section describes steps you must follow, as well as procedures the system

will automatically perform, after you replace a failed disk. As mentioned

previously, your system will continue to operate if a single disk drive within a

RAID 5 group fails. However, if your system experiences two or more disk

failures in the same RAID group, data loss may result.

Single Disk Failure Recovery

After you replace a failed disk drive within a RAID 5 group, the system will

begin an automatic rebuild of the RAID group. The data on the virtual disks

that reside on the RAID group are still available to your operating system and

your system should run without interruption. Until the rebuild operation

completes, the RAID 5 virtual disks will be running in degraded mode and are

at risk of data loss should an additional disk fail. Using OMSA, you can

monitor the progress and status of the RAID 5 rebuild. If the rebuild does not

begin automatically, refer to the "Rebuild a Failed Physical Disk" section of

the OpenManage™ Server Administrator User's Guide to initiate the rebuild

manually.

Figure 3-2 shows how OMSA reports the status of a rebuilding RAID group.
