Replacing a cluster disk with a VPATH device

Edit online

If you need to replace a cluster disk that has a VPATH device configured, before you use C-SPOC, move the PVID of the VPATH devices to the corresponding hdisks. This is done by converting the volume group from VPATH devices to hdisks. After converting, use the C-SPOC procedure to replace a disk.

About this task

Note: The C-SPOC disk replacement utility does not recognize VPATH devices. If you do not convert the volume group from VPATH to hdisk, then during the C-SPOC disk replacement procedure, PowerHA® SystemMirror® returns a no free disks message, although unused VPATH devices are available for replacement.

To replace a cluster disk that has a VPATH device configured, complete the following steps:

Procedure

  1. Convert the volume group from VPATHs to hdisks.
  2. Use the C-SPOC procedure to replace a cluster disk.
  3. Convert the volume group back to VPATH devices.
