232 HSG80 ACS Solution Software V8.8 for IBM AIX Installation and Configuration Guide
Output from miranda:
44...
You are going to want to use the greater of the two numbers, in this case 45.
7. Create the volume group on node brutus (all commands are on brutus until
otherwise specified) using the command:
mkvg -f -V 45 -s 32 -y sharedvg hdisk5
Note: The arguments to mkvg can and do 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.
The output should look similar to the following:
VOLUME GROUP: sharedvg
VG IDENTIFIER: 0002997f00004c00000000ec959cb382
VG STATE: active PP SIZE: 32 megabytes
VG PERMISSION: read/write TOTAL PPs: 31 (992 megabytes)
MAX LVs: 256 FREE PPs: 31 (992 megabytes)
LVs: 0 USED PPs: 0 (0 megabytes)
OPEN LVs: 0 QUORUM: 2
TOTAL PVs: 1 VG DESCRIPTORS: 2
STALE PVs: 0 STALE PPs: 0
ACTIVE PVs: 1 AUTO ON: yes
MAX PPs per PV: 1016 MAX PVs: 32
LTG size: 128 kilobytes AUTO SYNC: no
In this case, the number of free PPs is 31.
9. Create a logical volume using a command similar to
mklv -y sharedlv sharedvg 30
Note: We use the number of Free PPs - 1 because there needs to be 1 PP free to
create a filesystem.
