lvremove error

Prokopets — Fri, 03 Sep 2010 11:47:08 GMT

Hi!
I'm getting a strange issue with a logical volume on hp-ux 11.23, connected through fabric to EVA4400 (not only 4400, but anyway...). Here's where i began:

So, i have a problems with vg06 (it's not activated and, if i understand correctly, it's LUN is not presented to system any more. And one more problem with vg07 - it has only two paths. I checked the zoning twice, here's the output from fabric A:

So, i think zoning is ok. In EVA4400 CV configuraion this server following ports:

======
5006-0B00-0081-26BC
5006-0B00-0081-26AE
======

I'm not using this LUN, so i tried to delete it from system and unpresent from EVA, but got this error:

======
lvremove: Couldn't delete logical volume "/dev/vg07/flashdata1":
No such device or address
vgcfgbackup: Invalid LVMREC on Physical Volume /dev/rdsk/c22t0d1
======

As for vg06: i tried to activate it, but got this error

I think, vg06 was on LUN that was incorrectly unpresented from this server and now i have this error...

I have two questions:

1) What should i do with vg06? I think, i should delete it, but how?..
2) What should i do with vg07? I also want to delete this vg, but same question - how?

Regards,
Philipp.

Re: lvremove error

Duncan Edmonstone — Fri, 03 Sep 2010 11:52:07 GMT

so lvremove wants to write an updated LVM configuration to every disk in the VG - if you already un-presented the LUN on the EVA it can't do that...

if you know there's nothing you need in vg06, then just running:

vgexport vg06

will get rid of it for you (vgexport removes the VG from the LVM configuration, but doesn't attempt to update LVM configurations on the disks in the VG)

Same for vg07 if you've already un-presented those LUNs, otherwise the standrad lvremove/vgremove commands should work...

Duncan, thanks for help!

I did as you told me:

=========
bash-3.2# vgexport vg06
bash-3.2# vgexport vg07
vgexport: Volume group "vg07" is still active.
vgexport: Couldn't export volume group "vg07".
bash-3.2# /usr/sbin/vgchange -a n /dev/vg07
Volume group "/dev/vg07" has been successfully changed.
bash-3.2# vgexport vg07
=========

After that i unpresented LUN from EVA and now ioscan shows CLAIMED and NO_HW on "old" devices:

But what should i do with "dead" disks devices? I mean this ones:

Just use rmsf to get rid of the old device files which show NO_HW. The actual NO_HW entries in ioscan won't go away until you reboot, but they won't cause any issues...

Duncan, i've deleted all files, unpresented this LUN and presented it again with differend LUN number (3) to have a different h\w path. Now i'm facing with this picture:

========
bash-3.2# ioscan -fnC disk | grep HSV300
disk 63 0/2/1/0.4.4.0.0.0.1 sdisk NO_HW DEVICE HP HSV300
disk 64 0/2/1/0.4.5.0.0.0.1 sdisk NO_HW DEVICE HP HSV300
disk 71 0/2/1/0.4.5.0.0.0.3 sdisk CLAIMED DEVICE HP HSV300
disk 54 0/4/2/0.4.4.0.0.0.1 sdisk NO_HW DEVICE HP HSV300
disk 55 0/4/2/0.4.5.0.0.0.1 sdisk NO_HW DEVICE HP HSV300
disk 70 0/4/2/0.4.5.0.0.0.3 sdisk CLAIMED DEVICE HP HSV300
bash-3.2#
========

As i can see, both controllers can see new LUN: 0/2/1/0.4.5.0.0.0.3 and 0/4/2/0.4.5.0.0.0.3. But why there's only two paths? I don't think that it's a zoning issue or CV configuration - in that case only one controller will see the LUN... Any ideas?

Hi Philipp,

Logically it cant be anything else then a CV configuration error. As lun1 was successfully presented from the eva4400 to the hp-ux host, it cant be a zoning issue or a hp-ux host issue.

Unless offcourse the zoning config was changed after that lun1 was successfully presented to the host, then it could still be also a zoning configuration error.

But anyway, the first thing, I would change, is the use of the N_Port node wwid of the host fc hba, in the zoning config, I would still use the N_Port Port wwid of the fc hba in the zoning config instead.

For the rest, from the zoning config, I cant see which are the eva4400 fc "frontport" hba that are "zoned in" for the different fabrics. And if they are the "right" ones.

Do something like
# fcmsutil /dev/td0 devstat all |grep -i Nport_id

# fcmsutil /dev/td1 devstat all|grep -i Nport_id

If the fc hba's are correctly zoned in with the eva4400, then each host fc hba, should "see" "2 eva4400 fc hba frontports" Nport_ids , if this is not the case then something is wrong with the zoning config.

Finding out which Nport_id relates to which evaX frontport fc hba can be found through crosschecking fcmsutil /dev/tdX /switchshow/portshow/zoneshow/alishow output..

Greetz,
Chris

For LUNs that disappear (common with SANs), I would use rmsf -H. This will remove both the device files as well as the in-core cache for these missing LUNs. Don't use rm to delete non-existent device files.
