Disk device name with slice numer?

Jimmy Aulestia_2 — Mon, 20 Oct 2008 21:07:19 GMT

In the hpux 11v2 i have the device name in four disk with cxtxdxsx, the other disk have the device name cxtxdx.

In hpux the disk device name was cxtxdx, why only four disk have sx?

Example:

disk 14 0/0/8/1/0/4/0.1.0.0.0.0.3 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c7t0d3 /dev/dsk/c7t0d3s2 /dev/rdsk/c7t0d3 /dev/rdsk/c7t0d3s2
/dev/dsk/c7t0d3s1 /dev/dsk/c7t0d3s3 /dev/rdsk/c7t0d3s1 /dev/rdsk/c7t0d3s3

disk 19 0/0/8/1/0/4/0.1.0.0.0.0.5 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c7t0d5 /dev/rdsk/c7t0d5

disk 21 0/0/8/1/0/4/0.1.0.0.0.0.6 sdisk CLAIMED DEVICE HP HSV210
/dev/dsk/c7t0d6 /dev/rdsk/c7t0d6

hi,

only the boot disks generally have the s1/2/3 added to them.

that is because the boot disks need to be partitioned on the itanium systems. you are just seeing the dev files for each partition as well.

hpus is installed in the s2 partition

in itanium server partition of root disk is created like below
3
EFI 500MB
HPUX 100%
HPSP 400MB

thats why u will find diffrent slice on root disk.
