HPUX 10.20 missing pv path

[David Gwin]

Hi all,

I am working on configuring a backup system and in the process of setting up the disk drives with pvcreate I have found that I am missing the pvpath file.

I am missing
/dev/rdsk/c2t8d0
/dev/dsk/c2t8d0

I have all of the others but missing this one. How do I go about creating that device file?

Thank you
David

Hi David,

Check it with the following commands:
#ioscan -fnC disk |grep c2t8d0
# insf -eC disk

If you can't find the disks; try reseating the disks again, it may happen disks are not properly placed. Let me know if you see the disks.


Thanks,

oops... I did forget that one important note. I did a
ioscan -FnC disk

and it returned all of the disks and device files as expected EXCEPT for the one drive. The drive is lised but it does not have the dev files. The device does show up in sam as an unused device.

Hi David,

Check by ioscan -funC disk
If you find hardware path of this disk , you can use,

#insf -H hw-path

Or
#insf -e

Check below l ink in details,
http://docs.hp.com/en/B2355-90691/insf.1M.html

If it helps, pls assign point.

Hi,

Pls check the in /etc/lvmtab

strings /etc/lvmtab | grep "device path"

also check the
ioscan -fnC disk
if you are not able to see the missing path then run insf -e it will create the device path

Sorry, But I couldn't understand what you've said above, explain me so that I could suggest.
How did you check the drive is listed?

Thanks,

Unfortunately I do not have the system connected to the network at this time to give you the output of the ioscan -FnC disk. Basically, the output is as expected and the last two items listed for each disk is the /dev/rdsk/c2t#d0 and /dev/dsk/c2t#d0, however there are no dev files for the one drive.

I have managed to get the output into a file. Please look at the following trimed down (because of space) output.

ioscan -FnC disk
disk:sdisk:2/0/7.6.0:0 0 2 2 0 0 0 0 147 247 42 20 190 41 239 116 :3
/dev/dsk/c2t6d0 /dev/rdsk/c2t6d0
disk:sdisk:2/0/7.8.0:0 0 2 2 0 0 0 0 163 21 10 70 128 53 76 118 :9
disk:sdisk:2/0/7.10.0:0 0 2 2 0 0 0 0 163 21 10 70 78 24 121 187 :11
/dev/dsk/c2t10d0 /dev/rdsk/c2t10d0

ls /dev/dsk
c0t2d0
c2t0d0
c2t10d0
c2t12d0
c2t15d0
c2t1d0
c2t2d0
c2t3d0
c2t4d0
c2t5d0
c2t6d0
c2t9d0

I need to create c2t8d0 to get access to the one disk drive

Thank you to all
David

Did you do as Taifur suggested:

# insf -e

This is supposed to create device files.

[Mel Burslan]

insf -H 2/0/7.8.0

this should help
