Extend volume size
O/S : HP-UX 11.31
We have two servers which are in cluster and sharing the disk space from EVA as follws
/dev/vg02/lvol5 /oracle/PRD
/dev/vg02/lvol6 /oracle/PRD/data1
/dev/vg02/lvol7 /oracle/PRD/data2
/dev/vg02/lvol8 /oracle/PRD/data3
/dev/vg02/lvol9 /oracle/PRD/data4
Now I want to extend the size "/oracle/PRD" from 10gb to 20 gb.
I am new to HP-UX so how to do it please share your experience.
Thanks

Re: Extend volume size
Create a new 20 GB partition on the EVA and present it to the system.
Copy all data from /dev/vg02/lvol5 to the new partition.
Partition expansion is supported but its such a pain, this way is better.

Re: Extend volume size
First check for free space in vg02:
#vgdisplay vg02
and if you have just increase the size of the logical volume (lvol5).
How the data are shared between servers? Is that a cluster volume group?
regards,
ivan

Re: Extend volume size
Check if you have free space of 10GB in the volume group VG02.
Use # vgdisplay vg02 command to see the free space.
Free PE * PE size = Free space in MB
If you have enough space and online jfs product is installed you can extend it on the fly. No downtime or cluster modifications are required.

Re: Extend volume size
if you don't have free space in vg02 you can:
1. Extend LUN on EVA
2. use vgmodify command to change vg02 parameters like (-p -e ) - deactivation of vg02 will be required.
In cluster environment you need to change cluster flag for vg02 before applaying new parameters to vg02
3. extend lv size (lvextend command)
4. extend file system (fsadm or extendfs command)
Usefull documentation you can find here:
