Accessing a StorageTek 2530 Disk array from SUN, SPARC Enterprise T2000

Hello,
Wondering if anyone can help me with mounting a file share from my Sun T2000 server running Solaris 10 to my connected 2530 disk array?
I believe I've connected the disk array correctly and I have created a volume on the array using the filesystem (Sun_SAM-FS, RAID-5).
The T2000 server appears to see the disk array but not able to write a disk label or mount a filesystem on it as the following commands show:-
root@sesame # format

c4t0d0: configured with capacity of 1395.79GB

To be honest I've never attached an array to a Unix server before so any pointers would be appreciated.
Thanks, DD Smilie

why a SAM-FS? how do you configure the array (which software)?

Yeah I'm just using the Sun StorageTek Comman Array Manager Software

I was just trying some of the pre-defined file system types, here is the list to choose from.

I did format the array with Sun ZFS filesystem to start with but had no luck then.

So thought I'd try Sun_SAM-FS to see if that was any more compatible but no luck so far.

Was wanting a small block size as I want to put a lot of small files onto the disk array when I start using it.

The only documentation I've fun on how to configure the array has been :-
http://dlc.sun.com/pdf/820-2431-10/820-2431-10.pdf

And that says nothing about selecting the type of filesystem which would be most compatible with a SPARC Solaris 10 machine and how to go about actually mounting the file system to prepare it for use.

Cheers, Malcolm.

just stay with the default... unless you want to build a zpool from your luns or use samfs on your luns.

Will try formattting with the default option once I get past a new password problem:-
"The operation to unmap or delete volume ses_array_vol_01 failed. The operation cannot be completed because you did not provide a valid password. Open the Storage System's folder in the left hand navigational tree, click on the Administration folder, then click on Manage passwords and provide a valid Storage System password."

I have no idea what the valid storage system password would be, I never set one.

Nevermind it's nearly the weekend.

Update -
After a few minutes, I went to the Administration (Manage Passwords...) again, and I filled ONLY the fields (New Password, and Verify New Password), leaving the OLD password field (which is REQUIRED), blank. And I got a Success !!! blue i , great.

Reformatting array with default filesystem now... will try mounting the array again on Monday morning.

Re-created the disk array volume with the Default file system option and then tried again to mount the file system without success.

Anyone any suggestions where I'm going wrong?

Thanks, DD.

are you on the latest firmware for the array? i remember there were issues... also try a SMI label instead of the EFI label. just call "format -e" and choose SMI. also you've to build a FS before you can mount the new volume! read "man newfs" or "man zpool" if you are going to use ZFS.
