creating a new disk group in Tru64

Hello all;
I have an ES45 running Tru64 5.1b. A SmarArray 5300A with 1 existing 400gb lun (known as dg pdsdg) and I added 7 new 300gb disks to the shelf, created a second lun in the on board utility (1.34tb). Booted the system , it generated devices dsk2a,b,c,d..... all good so far.
I went disklabeled -nr /dev/rdisk/dsk2c. (entire disk)
Went into sysman- lsm management, created a new disk group (disk2dg) added my new disk dsk2c. Problem is it seems to have no free space available..
ie volassist -g disk2dg make space 40g

fails... ideas? did I miss something? thanks all.

Re: creating a new disk group in Tru64

Can you post the output of 'volprint'? What is the OS/patch version?

Re: creating a new disk group in Tru64


Hmm,

Personally I would step back and retry with presenting a lun less than 1TB, specially if you are going to carve it up later anyway.

You indicate v5.1b, which best I can tell should support 2TB drives, but still... why go where noone else has gone before?

The smartarray can present those 7 drives as mutliple luns no?

Here is what google found for +tru64 +"maximum disk":

"v5.1 has a 1TB limit. Anything larger starts to run into problems with
the disk drivers for the physical disks. The logical block address is
passed as a signed 32 number so (2^31 - 1) * 512 = 1TB-512. Anything
larger than that and negative values get passed into the device drivers
and they do bad things.


v5.1a w/pk3 and beyond can go up to 2TB, and then it will run out of
gas. The 32 bit value was made unsigned and any places in the drivers
where it would care, were fixed, so now the value can (2^32 -1) * 512 =
2TB-512.


If you have the AdvFS license, you can use addvol to create file systems
that can be up to 256TB in size (512TB on v5.1a w/pk3). Individual
files on AdvFS can be 16TB.


I do not know much about LSM. I do not know if LSM can create logical
volume greater than 1TB either before or after v5.1a w/pk3. Someone
with more LSM knowledge would have to provide that answer.

And Bob harris is 'the man'. Trust him.

You may also want to look at the SPD's but they appear not to cover 5.1b.
