So the disk has shown up as a pdisk but NOT an hdisk?
You need to go into smit and the change the disk from an 'array disk' to a 'system disk'. I forget the exact menus now. Start with: smitty ssaraid, I think.

Hi
Can I add disks on the fly to extend the capacity of an existing RAID 5 volume?
It's created on a 4P Advanced SSA Raid Adapter.

I am in the process of updating ssa adapters, drives and enclosures and wanted to know if there are any caveats that anyone would like to share. The documentation is not very clear on the ordering of the updates.
Any tips would be appreciated. (1 Reply)

Hi All,
What's the proper procedure for removing SSA arrays? Is the procedure like these?
- rmdev ssa disk
- physical turn off the ssa
- cfgmgr
There's no more filesystem or logical volume on it. It's just pdisk and hdisk.
Thanks in advance,
