Replacing a failed or removed disk

A different procedure is required to remove and replace a disk in a Sun StorEdge A5x00 or similar type of array.

See "Removing and replacing a disk in a Sun StorEdge A5x00 disk array" on page 131.

 To specify a disk that has replaced a failed or removed disk

1. Select menu item 5 (Replace a failed or removed disk) from the vxdiskadm main menu.
2. At the following prompt, enter the name of the disk to be replaced (or enter list for a list of disks):

   Replace a failed or removed disk

   Menu: VolumeManager/Disk/ReplaceDisk

VxVM INFO V-5-2-479 Use this menu operation to specify a

replacement disk for a disk that you removed with the "Remove

a disk for replacement" menu operation, or that failed during

use. You will be prompted for a disk name to replace and a disk

device to use as a replacement.
You can choose an uninitialized disk, in which case the disk

will be initialized, or you can choose a disk that you have

already initialized using the Add or initialize a disk menu

operation.

Select a removed or failed disk [<disk>,list,q,?] mydg02

3. The vxdiskadm program displays the device names of the disk devices available for use as replacement disks. Your system may use a device name that differs from the examples. Enter the device name of the disk or press Return to select the default device:

   The following devices are available as replacements:

   c0t1d0 c1t1d0

   You can choose one of these disks to replace mydg02.

   Choose "none" to initialize another disk to replace mydg02.

   Choose a device, or select "none"

   [<device>,none,q,?] (default: c0t1d0)

4. Depending on whether the replacement disk was previously initialized, perform the appropriate step from the following:
5. If the disk has not previously been initialized, press Return at the following prompt to replace the disk:

   VxVM INFO V-5-2-378 The requested operation is to initialize

   disk device c0t1d0 and to then use that device to

   replace the removed or failed disk mydg02 in disk group mydg.

   Continue with operation? [y,n,q,?] (default: y)

6. If the disk has already been initialized, press Return at the following prompt to replace the disk:

   VxVM INFO V-5-2-382 The requested operation is to use the

   initialized device c0t1d0 to replace the removed or

   failed disk mydg02 in disk group mydg.

   Continue with operation? [y,n,q,?] (default: y)

7. If the disk was previously an encapsulated root disk, vxdiskadm displays the following message. Enter y to confirm that you want to reinitialize the disk:

   VxVM INFO V-5-2-876 The disk c0t1d0 was a previously

   encapsulated root disk. Due to the disk layout that results

   from root disk encapsulation, the preferred action is to

   reinitialize and reorganize this disk. However, if you have

   any non-redundant data on this disk you should not reorganize

   this disk, as the data will be lost.

   Reorganize the disk? [y,n,q,?] (default: y) y

   Warning: It is recommended that you do not enter n at this prompt. This can result in an invalid VTOC that makes the disk unbootable.
   
   Entering y at the prompt destroys any data that is on the disk. Ensure that you have at least one valid copy of the data on other disks before proceeding.
   
5. You can now choose whether the disk is to be formatted as a CDS disk that is portable between different operating systems, or as a non-portable sliced or simple disk:

   Enter the desired format [cdsdisk,sliced,simple,q,?]

   (default: cdsdisk)

   Enter the format that is appropriate for your needs. In most cases, this is the default format, cdsdisk.

6. At the following prompt, vxdiskadm asks if you want to use the default private region size of 65536 blocks (32 MB). Press Return to confirm that you want to use the default value, or enter a different value. (The maximum value that you can specify is 524288 blocks.)

   Enter desired private region length [<privlen>,q,?]

   (default: 65536)

7. The vxdiskadm program then proceeds to replace the disk, and returns the following message on success:

   VxVM NOTICE V-5-2-158 Disk replacement completed successfully.

   At the following prompt, indicate whether you want to replace another disk (y) or return to the vxdiskadm main menu (n):

   Replace another disk? [y,n,q,?] (default: n)
