question on adding new disks to rp5470 server

[Gino Castoldi_2]

Hi,

Server: HPUX 11.11 rp5470 36GB LVD disks

We added two internal disks to our server.
I ran ioscan -fnC disk and I see the disks and the h/w paths.

Question: what do I do next to create the disk devices themselves? (/dev/dsk/c#t#d3)

# ioscan -fnC disk
Class I H/W Path Driver S/W State H/W Type Description
=============================================================
disk 27 0/0/1/1.0.0 sdisk CLAIMED DEVICE SEAGATE ST336704LC

The command you need is "insf".
If you want to restrict it to disk devices only (just to be safe), then "insf -C disk"

Hi,

Should I run the "insf" command like this?
root# insf -e -H 0/0/1/1.0.0

insf will create device files, e.g. c1t2d0.

Now you can create a PV (pvcreate), create or extend a volume group - this is up to your needs.

If you wish; that works too. However, simple "insf" with no options will automatically create device files for all devices that don't have them yet. If the addition of two disks is the only hardware change, just "insf" creates devices for both disks at once and is much shorter to type :)

If your /dev/dsk and/or /dev/rdsk directories have some old device files that have not been removed properly (e.g. ioinit was run for some reason, or this system was cloned from an Ignite image), then the "-e" option may be useful: it permits insf to delete any existing device files with the same name, and then create the correct device file(s) using standard names, device numbers & permissions.

Hi,

You can also run as

# insf -e -C disk

it will create device files for your disks or if you dont want to run it on entire disk class, then you can create as you written above (by specifying the h/w path).
