Configure raid devices - logical volumes 6402

[Ratzie]

I have a MSA30 with an 6402 Smart Array controller.
Thru saconfig I have created 6 RAID 1 devices.
Which come up logical devices.

# RAID Size Status

0 1+0 69460 MB OK
1 1+0 69460 MB OK
2 1+0 69460 MB OK
3 1+0 69460 MB OK
4 1+0 69460 MB OK
5 1+0 69460 MB OK


I can not see any of these devices in SAM to create volume groups.
It comes up as one logical volume.

0/4/1/0/4/0.0.0 6 Unused -- 69460 HP

I need to create a volume group on each RAID slice.

If you created the new RAIDs online, you now need to create the device files (insf -e).

Check with "ioscan -fnCdisk".

ioscan lists the disks, but I can not see them in SAM.
It just shows one logical volume and only 72GB.
I have 6 RAID 1 logical sets.

SAM is showing 1 LUN with 6 pathes - this looks wrong. Patches needed? Check this.

Your LUN6 is missing!

You may just go ahead and use pvcreate, vgcreate, lvcreate ...

Ahhh the command line, the command line is your friend.
For some reason SAM did not pick up the disks.

After I created the physical volumes from command line, SAM had no problem.

ioscan -fnC disk
# pvcreate /dev/rdsk/c5t0d0
# mkdir /dev/vg01
# cd /dev/vg01
# mknod group c 64 0x010000
# vgcreate vg01 /dev/dsk/c5t0d0
# vgdisplay -v /dev/vg01

I did not have a problem with LUN 6, I just never created a RAID 0 device with it yet.
saconfig /dev/ciss5 -R 0 -p 2:8

LUN6 was showing NO_HW!

I would look for a current sam cumulative patch ... btw, 0 points = useless?
