Raid 5 Modification
We get a rx2660 server running 11iv2 with several disks with same capacity (146Go) controlled by a raid 1 controler (HPUX Ref AD248A).
Three of them are configured in raid 5 mode (/dev/vg01), and one is alone (static data)(/dev/vg02).
I would like to increase the capacity of /dev/vg01, by deleting /dev/vg02 and adding the 'free' disk to /dev/vg01, to get finally four disks (146Go) in raid 5 mode.
Question:
Is this possible to do it with saconfig tool in live mode (without deleting any data or current raid 5 configuration or stopping the data access) , if yes with which options ?
Regards,

Re: Raid 5 Modification
Remove vg02 (e.g. vgexport); delete logical drive 2 (disk detail
Participating Physical Disk(s)...... Ct:Enc:Bay:WWID
1I:1:6:0x5000c50006a63a8d
Now add this unused disk to logical drive 1 - online.
Once the disk is added, you can increase the size, e.g.
# saconfig /dev/ciss3 -E 1 -c 100
Logical drive 1 extended from 87.9 GB to 100 GB in capacity
Now you need to adjust LVM structure with vgmodify - this is offline (vg deactivated!)
Hope this helps!
Regards
Torsten.
