4. On node miranda, execute the command:
chdev -a pv=yes -l hdisk4
5. Using the lspv command, examine the PVID on each disk to make sure that
they are the same.
The output from brutus displays as:
hdisk0 0002997fb3fcfab5 None
hdisk1 0002997f32d9425d rootvg
hdisk2 none None
hdisk3 none None
hdisk4 none None
hdisk5 0002997f95945b06 None
hdisk6 none None
The output from miranda displays as:
hdisk0 0000981f0ebaf585 None
hdisk1 0000981f6f1f38bb None
hdisk2 0000981f6c12e583 rootvg
hdisk3 none None
hdisk4 0002997f95945b06 None
hdisk5 none None
6. Execute the command lvlstmajor on each node in the cluster to get the
next available major number to use for a volume group:
The output from brutus displays as:
45...
The output from miranda displays as:
44...
Use the greater of the two numbers, in this case 45.
7. Create the volume group on node brutus using the command:
mkvg -f -V 45 -s 32 -y sharedvg hdisk5
Note: All commands after this step are executed on brutus unless otherwise specified.
The arguments to mkvg can and will vary. Use arguments that are appropriate to the
size and purpose of your device.
8. Execute the command lsvg sharedvg to get the number of Free Physical
Partitions.
This number can be found in the FREE PPs: field.
