SUN A1000 array disks - how to make them show up in format

I believe st.conf is for tapes...

do you have raid manager installed?

what version of solaris and whal level obp?

just found a link that may help!

A1000 has hardware raid built in, you need to install RM6 to see all the disk in the A1000 (install the SUNWosafw package) for your version of OS.
have a look at: (you can download it from the same site)
http://www.sun.com/storagetek/management_software/raid_manager.html
if you are running Solaris 10, have a look at:
http://unix.derkeiler.com/Mailing-Lists/SunManagers/2005-10/0052.html
 

Basically, you will never see the individual disks of the array in Solaris. The A1000 is a hardware raid and the array controller combines the physical disks into LUNs that are presented to the OS.

RM6 (Raid manager) is used to create LUNs out of the physical disks. E.g. if you configure 6 x 36GB disks into a RAID5, the OS will see one single disk of about 180GB. The 36GB disks never show up in format.

I have solaris 10 installed on a blade 1000 and rm6 installed.
I can see all of the disks through the rm6 but was looking for a way for them to be seen in the format command as individual disks instead of just one disk.
What happens if you downgrade the A1000 to a D1000?

Would SUN's CAM software work on an A1000?

The D1000 was a JBOD (just a bunch of disks), and yes, the disks inside are presented to the OS.

However you loose the performance of the Hardware Raid Controller and the controller cache, so it would be much slower. This is not recommended.

The A1000 is quite an old beast and is no longer supported. So forget about using recent software like CAM.

Can you tell me then how I access the array disks from the OS?
I wanted to put some database files there but I am used to seeing disks as mounted files systems.  I would format the drive then do a newfs and then mount it.
Thanks
 

Use the RM6 utility to create one or more LUNs out of the A1000 disks, depending on your needs (e.g. one big LUN, 2 or more smaller LUNs).

These LUNs will show up as (large) disks in Solaris, in format you may see something like:

c69t0d0 <Symbios-StorEDGEA1000-0101 cyl 2005 alt 2 hd 64 sec 64>

You can format, partition and use them *as regular disks*.

If you partition a LUN into 7 slices, you can mount up to 7 filesystems on a single LUN.

I had tried setting up 12 different luns (I have 12 disks in the array ) but still only saw one in the format command.  I must be doing something wrong.
I will go back and try again.

You probably need to use devfsadm to make the new devices visible.

Anyway, 12 LUNs is way too much. Configure at most 2 or 3 RAID5 LUNs. Assign one drive as hot spare.

robocat thanks - I will look up how to use devfsadm and try to reconfigure the luns this afternoon.

I still only see one disk for the array..............

There is definitely more that 94 meg on these disks.....
 
Any ideas?

In the rm6 utility -> configuration ->controller A, you see your groups/luns.

-How many luns do you see?
-for each LUN:
     -which are the associated drives ?
     -what is the capacity of the LUN ?

I see one lun and 12 drives capacity is for each drive listed in rm6 is 35003Mb

The LUN capacity is listed ad 10Mb - don't understand why

Did you create a LUN consisting out of 12 drives or are the drives unassigned ?

the drives are assigned to the one lun

I installed all the patches I could find - sun's site was kind of confusing about which should be applied because it is so out of date.
So - delete the current lun config and redo?

>So - delete the current lun config and redo?

Yes, if I remember correctly you can even reset the entire array config.

Thanks I finally got it to work.
