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.

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

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

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

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

Use vxdiskadm option 1, or VEA.

3. Add a volume to this disk:

Use vxassist or VEA.

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

1. Get the current boot disk:

# cat /stand/bootconf

2. Extract resultant device path:

# ioscan -k node_path_from_bootconf
