Physical Disk Naming

VxVM parses disk names to retrieve connectivity information for disks. Operating systems have different conventions:

Solaris
/dev/[r]dsk/c#t#d#s#

HP-UX
/dev/[r]dsk/c#t#d#

AIX
/dev/hdisk#

Linux
SCSI –
/dev/sda[1-4] – primary partitions
/dev/sda[5 – 16] – logical partitions
/dev/sdb# - on the second disk
/dev/sdc# - on the third disk

IDE –
/dev/had#, /dev/hdb#, /dev/hdc#
