Odd drive paths

I'm settling into a new position and was checking on the drive mirroring on our rp7420 systems. It has two drives at drive paths:


that appear to be the root drives and appear to be mirroring one another. The machine has two drives physically located at the top right and top left internally.

http://docs.hp.com/en/A7025-96024/A7025-96024.pdf indicates that the physical drives on an rp7420 should have paths as:

1/0/0/3/0.6.0 (top left)
1/0/0/3/0.5.0 (top right)
0/0/0/3/0.6.0 (bottom left)
0/0/0/3/0.5.0 (bottom right)

I did see a drive path in another forum post of the format 1/0/1/0/0/1/1.6 which is similar, but that was an rp7410.

Is this correct for an rp7420? Does it have something to do with having two cell boards? I do not believe the machine is partitioned.

Re: Odd drive paths

Well, what is the question now?

Where is disk 1/0/1/1/0/1/1.6.0 ?

It is a disk connected to a HBA in slot 8 (cell 1 connected I/O) - the core I/O.

This is the top right disk.

is the top left disk.

Hope this helps!

Re: Odd drive paths

for all 2 cell based servers rp74xx and rx76xx
the hardware addresses for the internal disk are as follows
left 1/0/0/3/0.6
right 1/0/1/0/0/1/1.6
left 0/0/0/3/0.6
right 0/0/0/3/0.5
the strange addressing of the top right disk is because it is connected to the PCI LAN/SCSI coreio installed in slot 8.
so you notice that the top disks belong to cell 1 and the bottom to cell 0 so it has nothing to do whether they are partitioned or not, or if they are one partition.

i advice u to recheck the second disk hardware cuz i think you've copied it wrong.
