New SAS disk installation for DRD

[Jeongbae Min]

Hello,

I just learned HP-UX 11.31 support DRD function.
so I'd like to add new SAS disk to rx3600 server. Its SAS array has number from 1 to 8 and current root volume disks are plugged in number 7 and 8.
My question is
Do I need to add next disk to number 6?
and the server will recognize disk right away after I add it into SAS array?


Thank you in advance.

Just insert the disk where ever you want and run ioscan and insf. I would prefer the first slot.

yeh just get the disk device file after inserting and ioscan an insf.
Use the new device file to be used for DRD.

Hello,

SAS controllers use unique addressing scheme which is quite different from SCSI.

If you pull out a SAS disk and attach to a different slot or bay, the device files remain same..due to unique addressing of disks.

At the same time if u connect a replacement disk for a disk that's gone bad then the device files gets changes.

But in your case you are just adding a new disk/array , so you can straight away use the new device files for creation of the PV.
