Adding SAS drives


rx3600 server running 11.31 with IR supporting 2 volumes of 2 disks each in RAID 1.

Before today one volume of 2x70gb SAS drives existed in bays 7 and 8.

Today I added a second volume of 2x70gb SAS drives in bays 5 and 6.

After physically adding the drives and seeing the flashing green light, I ran the following command to create the new volume:

sasmgr add -D /dev/sasd0 -q raid -q level=1 -q enc_bay=1:5,1:6

I had read that leaving out the size parameter creates the volume at max size.

The logical volume was created as expected but ioscan output now shows two IR volumes (as expected) but also two new sdisk No_HW devices with descriptions of EH0072FARWC and each having their own device files -- the first IR volume did not have these types of associated entries.

Any ideas on what happened or how I can fix this?

Output attached.

Re: Adding SAS drives

The system remembers the disks directly attached.

disk 4 0/4/1/0.0.0.1.0 sdisk NO_HW DEVICE HP EH0072FARWC
/dev/dsk/c0t1d0 /dev/rdsk/c0t1d0
disk 19 0/4/1/0.0.0.2.0 sdisk NO_HW DEVICE HP EH0072FARWC
/dev/dsk/c0t2d0 /dev/rdsk/c0t2d0

After the next reboot they will disappear.

Meanwhile you can try

rmsf -k -H 0/4/1/0.0.0.1.0

to remove this information from kernel.




As said, reboot will solve this too.

Hope this helps!
Regards
Torsten.
