On my SunOS 5.10 host are there 3 Sun 6140 disk arrays, and I would like to know the disk capacities.

According to zpool list do I have a 5TB and 16TB pool. format shows me only 12 disks

c2t1d31: configured with capacity of 16.00MB
c3t4d31: configured with capacity of 16.00MB
c5t4d31: configured with capacity of 16.00MB
c6t1d31: configured with capacity of 16.00MB

and what is strange here is that format claims the disks are larger than 1TB, which can not be the case according to the 6140 datasheet.

/etc/hosts contain

#6140 Disk array
10.0.68.65
10.0.68.66
10.0.68.67
10.0.68.68

where all can be ping'ed.

I don't see any RAID with zpool status

Question

As each 6140 have 16 disks, I would expect to see 3x16 disks, but I only see 12 which larger capacity then the datasheet allows, and I don't see any raid configured. And way are the reported disk sizes so different from disk to disk?

How do I find the disks real capacity?

You're expecting a JBOD, but it appears that this might be set up as a SAN, and you're seeing LUNs. You should check the 6140s themselves.

  • Yes it is a SAN. Why would it be configured with LUNs and not just as a JBOD?

    Terminology matters here- a SAN is technically the entire network for the storage- all the switching, storage controllers, and client hookups (like HBAs and blade interconnects). A JBOD can live in a SAN, but rarely does. A JBOD is almost always directly attached to a server, and relies on the server's RAID card to control the disks. A more commonly seen setup is where the disk controller has its own raid management system and provides virtual disks (LUNs) to whatever servers connect to it.

If you think the OS is lying to you, you can run this

zfs list

It will show you how much space ZFS has available from those disks.
