re: rebuilding K570 server and "Model 20" storage array
# strings /etc/lvmtab
/dev/vg00
/dev/dsk/c0t1d0
/dev/dsk/c1t0d0
i have setup vg01 and vg02 with the appropriate permissions and created a group file as well.
I have used pvcreate to initialize the other disks but receive the error
# pvcreate -f /dsk/rdsk/c0t1d2
Couldn't stat physical volume "/dsk/rdsk/c0t1d2":
Physical volume can be created only on whole disk.
I have had to unbind and then bind the disks on the array.
When i run a ioscan this is the output i get :
ioscan -fnkC disk

Re: re: rebuilding K570 server and "Model 20" storage array
2. I notice there's LUN 3 is missing in sequence. Of course it's not a requirement, but as a test try creating LUN 3 and see if it will help. If it will help - then you probably are missing some SCSI cumulative patches...

Re: re: rebuilding K570 server and "Model 20" storage array
Grid manager is a serial interface of disk array controllers. If you would connect to any controllers' serial port using 9600/8/N/1 (using, for example, 700/96 terminal) you'll get into controller firmware where you can view configuration and manage array.
I think for the first time try SAM. If it will not work - connect to serial port and check which LUNs are there. Please do not modify anything from grid manager

Re: re: rebuilding K570 server and "Model 20" storage array
step 1 - thru sam
highlight disk array controller at 8/12.0, select 8 disks to bind using raid 1/0,
highlight disk array controller at 8/8.1,
select 8 disks to bind using raid 1/0,
why is it not claiming all the disks?

Re: re: rebuilding K570 server and "Model 20" storage array
To create LUN you need to use 'bind' option and select unused disks. And give new LUN a number - I would like you to create LUN 3. And check if there're really LUNs 4, 5, 6, 7 exist in disk array...

Re: re: rebuilding K570 server and "Model 20" storage array
# vgcreate /dev/vg01 /dev/dsk/c0t1d1
vgcreate: IO error on Physical Volume device /dev/dsk/c0t1d1
i pvcreated the disk and that runs ok
# pvcreate -f /dev/rdsk/c0t1d1
Physical volume "/dev/rdsk/c0t1d1" has been successfully created.
i then re-ran the vgcreate command and received the following message
# vgcreate /dev/vg01 /dev/dsk/c0t1d1
Increased the number of physical extents per physical volume to 4252.
vgcreate: Volume group "/dev/vg01" could not be created:
The path does not specify a valid physical volume.
the vgdisplay command returns the following -
# vgdisplay -v /dev/vg01
vgdisplay: Volume group "/dev/vg01" does not exist in the "/etc/lvmtab" file.
vgdisplay: Cannot display volume group "/dev/vg01".
any suggestions on where im going wrong?
