rx2660 logical drive not detected
i was trying to setup my server with the following smart array configuration:
two 36GB disks in raid 1+0 (bays 7 and 8)
one 72GB disk in raid 0 (bay 6)
one 72GB disk in raid 0 (bay 5)
note that the two raid 0 disks are not "connected", they are supposed to be used as independent logical volumes.
when on the smart array utility i finish the configuration, all the logical drives apear ok, and i have 3 entries as described previously. The problem is that when i start the LVM (using SAM -> disks and file systems) the two 72GB disks, do not appear. Instead an entry of 72GB appears, and has two paths instead of one.
How do i setup the system, so that i can use the 72GB disks, independently?
best regards
Miguel Rentes

Re: rx2660 logical drive not detected
# ioscan -fn
(assuming cissx is the controller device file)
# saconfig /dev/ciss3
# sautil /dev/ciss3
Hope this helps!
Regards
Torsten.

Re: rx2660 logical drive not detected
The internal smart array is both a raid controller and a simple SAS controller. You don't have to make the disks in bays 5 and 6 RAID0, you leave them alone and they will show up as individual disks outside of the RAID controller.
You can either check the disks with ioscan or delete the two raid0 LUNs within the smart array.

Re: rx2660 logical drive not detected
disk 0 0/0/2/1.0.16.0.0 /dev/dsk/c0t0d0 (which is the CD-ROM)
disk 1 0/3/0/0/0/0.0.0 sdisk
/dev/dsk/c1t0d0 /dev/dsk/c1t0d0s1 /dev/dsk/c1t0d0s2 /dev/dsk/c1t0d0s3 /dev/rdsk/c1t0d0 /dev/rdsk/c1t0d0s1 /dev/rdsk/c1t0d0s2 /dev/rdsk/c1t0d0s3
(which is the logical drive for the two 36 GB disks)
This tells me that those two 72 GB disks are not detected :S Should I try to create a logical drive for each disk in a different manner (one first than the other perhaps)?
Best regards

Re: rx2660 logical drive not detected
or
delete the two RAID0 luns and rerun "ioscan" without the -k option and the two disks should show up as standalone disks.

Re: rx2660 logical drive not detected
Is the "normal standard" SAS controller installed or the SmartArray P400?
Everything else depends on this.
Hope this helps!

Torsten.

Re: rx2660 logical drive not detected
I read the documentation for the saconfig and the pdf "Managing Disks and File Systems" and was able to create all volume groups/name I wanted with vgcreate/mknod/etc... I was assuming sam could do everything with the disks but using the command line was much more easier.
Anyway, thanks for your help.
Best regards,
Miguel Rentes
