Creating CDS Disks from Initialized VxVM Disks

If the disk is already initialized, there are two cases to consider:

• Disk Not in a Disk Group
• Disk Already in a Disk Group

Disk Not in a Disk Group

If the disk is not in a disk group:

1. Run the following command to remove the VM disk format for the disk:
   # vxdiskunsetup disk

   This is necessary as non-auto types cannot be reinitialized by vxdisksetup.

2. If the disk is listed in the /etc/vx/darecs file, remove its disk access (DA) record using the command:
   # vxdisk rm disk

   (Disk access records that cannot be configured by scanning the disks are stored in an ordinary file, /etc/vx/darecs, in the root file system. Refer to the vxintro(1M) manual page for more information.)

3. Rescan for the disk using this command:
   # vxdisk scandisks
4. Finally, run this command to set up the disk:
   # vxdisksetup -i disk

Disk Already in a Disk Group

If the disk is already in a disk group, run vxcdsconvert, as described in Converting a Non-CDS Disk to a CDS Disk.
