Our current system has a 67GB RAID volume configured as a single volume group and single logical volume. The data is arranged in a RAID 5 configuration (stripe w/ parity). I will be adding 33GB to the RAID and the RAID system can automatically take care of adding the drive and re-striping the data, etc.
My concern is how to modify the HP volume group and/or logical volume to take advantage of this new space.
Is it as simple as using lvextend and extendfs?? This works great when you extend a LV with disk space that already existed on the volume group. In my case, the volume group has actually changed in size.
Any help is greatly appreciated. I am running on a K460 with HPUX 11.00. The RAID system is an LSI E2400 (aka StorageTek D173).
Thank you,
John Sherman

Re: Adding disks to a RAID logical volume
In order to recognize them, you'll have to do
#ioscan -fnC disk
#insf -e
to create the disk device files for those new disks.
Take note, of the new disks that you just installed, then
#vgextend vgname /dev/dsk/newdisks
After that you can do the lvextend command
#lvextend -L 100000 /dev/vgname/lvname
and if you have Online JFS, you just have to use the fsadm command to extend the file system, otherwise, you'll have to unmount the file system and then do the extendfs command.

Re: Adding disks to a RAID logical volume
Is it possible, with the LSI E2400 to assign the new disk capacity to a new LUN. In this case this LUN can be added to the volumegroup as a new disk.

Re: Adding disks to a RAID logical volume
If per disk then Leif is correct.

Re: Adding disks to a RAID logical volume
This sounds great but I recall reading that you cannot increase the size of a LUN. Therefore, I am a little skeptical of counting on this.
Any thoughts?
