Maintaining a Storage Array
103
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.
Redistributing Virtual Disks
Redistributing virtual disks returns the virtual disks to their preferred RAID
controller module owners. The preferred RAID controller module ownership
of a virtual disk or disk group is the RAID controller module of an active-
active pair that is designated to own the virtual disks. The preferred owner for
a virtual disk is initially designated when the virtual disk is created. If the
preferred RAID controller module is being replaced or undergoing a firmware
download, ownership of the virtual disks is automatically shifted to the
second RAID controller module. The second RAID controller module
becomes the current owner of the virtual disks. This change is considered to
be a routine ownership change and is reported in the MEL.
CAUTION:
Ensure that a multipath driver is installed, or the virtual disks are not
accessible.
