Maximum Partition Size on 5.1B-4



More out of curiosity than anything else...

I have been wondering what the maximum partition size is on the current
version of Tru64. I know this has been discussed before, but I wanted to
correlate it with our observations...

The SPD still gives the maximum partition size as 1TB-512K, but
elsewhere it's suggested that the limit was raised to 2TB - for example
this posting on comp.os.tru64:

http://groups.google.com/group/comp.unix.tru64/browse_thread/thread/ea88de7ddadaabc9/7cc48d8caa4f270f?lnk=st&q=tru64+maximum+disk+size&rnum=1#7cc48d8caa4f270f

We have a couple of alphaservers (a DS20 and an ES40) connected with
KGPSA-CA HBAs to an EMC Clariion CX300. All firmware is current (SRM
7.2-1 and KGPSA-CA version 3.93A0), and they are running 5.1B-4. Our
observation is that disklabel can only manage a disk of <1TB (probably
the SPD value of 1TB-512K.

We have three disks set up on the array, of 1000MB, 1TB and 2TB.
disklabel can write a label to the first, but returns "disklabel:
cannot determine disk type." for the others.

So is the information about the raised 2TB limit maybe incorrect? Or
does it depend on the particular HBA and driver?
