Adding Dump Volumes Using Volume Manager Disks

Volume Manager volumes can be used for additional dump volumes in configurations with LVM or

VxVM root disks.

Step 1. Remove a disk from LVM control. Execute the following:

# pvcreate -f /dev/rdsk/c#t#d#

# pvremove /dev/rdsk/c#t#d#

Step 2. Put a disk under Volume Manager control and place in rootdg:

Use vxdiskadm option 1, or VEA.

Step 3. Add a volume to this disk:

Use vxassist or VEA.

Step 4. Add the new volume as a target for dumps:

First make sure you have the PHKL_27096 patch, then use crashconf as you would under LVM.

For example;

# crashconf /dev/vx/dsk/rootdg/your_dump_volume

Changing the Boot Disk to be the New Volume Manager Root Disk

Step 1. Get the current boot disk:

# cat /stand/bootconf

Step 2. Extract resultant device path:

# ioscan -k node_path_from_bootconf

Step 3. Change primary boot path back to current boot device:

# setboot -p device_path_from_above

(Use -a if you want to change the alternate bootpath.)
