FC60 Storage Array - adding disks to existing volume groups

Gurinder Bhandal_1 — Tue, 10 Jun 2003 14:43:14 GMT

I would like to add a spare hotswap disk to an existing volume group. The existing volume group is RAID 5. I presume this can done via FC60 management software (NT 4 server). Would I need to delete the existing volume group and recreate a new volume group (including the hotswap disk) and then restore the data or can I just dynamically assign the spare disk to the existing volume group. I need step by instructions. I have some FC60 user guides, however they do not have ay instructions on how I can accomplish this task.

1. backup LUN data;
2. delete GHS (move it to 'unassigned' state);
3. remove LUN;
4. bind new LUN with previous LUN disks and this former GHS;
5. restore data
Remember: for redundancy reason bind disks residing on different SCSI channels. If you'll bind 2 disks on the same channel then if channel will go offline RAID LUN will be non-accessible (alhough if you'll get this situation some time please do not do anything by yourself - call HP and they will restore LUN's health)
