Reconstructing a Physical Disk
If two or more physical disks in a disk group have failed, the virtual disk shows
a status of Failed. All of the virtual disks in the disk group are no longer
operating. To return the disk group to an Optimal status, you must replace
the failed physical disks. After replacing the physical disks, reconstruct the
data on physical disks. The reconstructed data is the data as it would appear
on the failed physical disks.
To reconstruct a physical disk, run the following command:
start physicalDisk [
enclosureID
,
slotID
]
reconstruct
where,
enclosureID
and
slotID
are the identifiers for the physical disk.
NOTE:
You can use this command only when the physical disk is assigned to a
RAID 1, 5, or 6 disk group.
Initializing a Virtual Disk
CAUTION:
When you initialize a virtual disk, all data on the virtual disk and all
information about the virtual disk are erased.
A virtual disk is automatically initialized when you first create it. If the virtual
disk starts exhibiting failures, you might be required to re-initialize the virtual
disk to correct the failure condition.
The initialization process cannot be cancelled once it has begun. This option
cannot be used if any modification operations are in progress on the virtual
disk or disk group. To initialize a virtual disk, run the following command:
start virtualDisk [
virtualDiskName
] initialize
where,
virtualDiskName
is the identifier for the virtual disk.
