OBP - root / mirror disk syntax
Hi all

Can someone explain to me the different syntax regarding how root / mirror disks are represented. I never truely understand the namely / device tress etc.

Let me give you an example. On one my my servers, the root and mirror drives are :-

A domain on a sunfire 6800 :-
devalias vx-rootdisk /ssm@0,0/pci@1a,700000/pci@1/SUNW,isptwo@4/sd@0,0:a
devalias vx-rootmirror /ssm@0,0/pci@1a,700000/pci@1/SUNW,isptwo@4/sd@1,0:a


On another server, a v880 the root / mirror drives are :-

devalias sds-mirror /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@1,0
devalias sds-disk /pci@8,600000/SUNW,qlc@2/fp@0,0/disk@0,0


On another server, a 280, the root / mirror are :-

nvramrc=devalias mirror /devices/pci@8,600000/SUNW,qlc@4/fp@0,0/ssd@w500000e010bfd1d1,0:a

i.e. some have :a or :b or :c on the end of the device path. Why's this ? Is it hardware related ? when it says disk0,0 Im assuming its disk 0, slice 0 ?

How come the dfference in naming ?? This always gets me, and Ive never really truely known why this is.

Cheers
