HDD replacement with greater capacity in HP-UX

[yudhichandra]

Hi all,

Can anyone guide me through the procedure for replace 4 HDD with 4 new HDD with bigger capacity in rx2660

Data will be destroyed is not a problem, as I will restore it from other server.

Thank you.

If you want to restore a backup anyway, then delete the logical drives, swap the disks and create new logical drives.

[yudhichandra]

No need to delete PV and RAID 5 configuration?

IMHO it will work if you shutdown the server, pull all the disks, insert the new disks and start from scratch (creating arrays, logival drives, restore your backup).
