How to rename disks in HP-UX 11iV3 / 11.31

[Holger Nieraad]

Hello,

is it possible to rename disks in 11.31? For example: disk45 to disk10 ?
I know this is possible in Tru64 with #dsfmgr.
But this tool is not implemented in HP-UX.

regards

HN,

Disk names are diffrent in HP-UX than Tru64. If you will issue a ioscan -fnCdisk you will find disk name in format /dev/dsk/c#t#d#.
c# â The number of the controller to which the disk drive is attached (used on HP-UX systems)

t# and d# â The target ID and device number that constitute the address of the disk drive on the controller (used on HP-UX systems)

s2 â The HP-UX partition number on the boot disk drive (used on HP-UX 11i Version 1.5 systems)

Add on:
Furthe disk can utilize in LVM or VxVM, there you can create logical partitions and name as per your choice.

I use the new agile view in 11.31.
So, i find disk45 and would rename it to disk10.


# ioscan -funC disk -N

Hi,

You may want to use the command io_redirect_dsf (1M). See http://docs.fc.hp.com/en/B2355-60130/io_redirect_dsf.1M.html

Example:
io_redirect_dsf -d /dev/disk/disk23 -n /dev/disk/disk26

By the way, ioinit -f is another possibility to do the same.
See ioinit(1m).

Hi Holger,

See the 11iv3 LVM management also few things to consider as well (see steps 1-10)

Shalom,

Disk renaming procedures, which are really instance re-numbering procedures have limited ability to change the name's of disks.

However if all the disks in your system were present at first install, you are unlikely to get meaningful change from this risky procedure.

Far better than that is using lvcreate -n name to name logical volumes in a fashion that you prefer.

Hello & thanks,

io_redirect_dsf -d /dev/disk/disk23 -n /dev/disk/disk26 works only, when dsf (here 26) is present.
In my case it was not, and i try it with ioinit -f -> reboot. And this works.
Thanks for all hints in this case
