vgdisplay showing errors

[jtran]

I have have a rp4440 with 2 x HBA.
A failed HBA was replaced recently and switch rezoned to accomodate the new WWN.

I have done a vgscan -a -v to scan for all new paths and to update the /etc/lvmtab

However when I do a vgscan -v , I am getting errors:

vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c5t0d1":
The specified path does not correspond to physical volume attached to
this volume group
vgdisplay: Warning: couldn't query all of the physical volumes.

/dev/dsk/c5t0d1 is the altenate path via the replaced HBA, but vgdisplay is showing errors?

It is also showing PV as 1, while it should be 2.

Hi Johnny,

What is the status of the card in ioscan, is it in claimed status ?
Have u check the same disk from the other path is it working fine ?
Can you check if the SCSI id for the replaced HBA card ?
Check the cable also..

The disk is working via the other path.

In SAM, it shows the primary and alternate path as well.

Hello Jhonny,

could you check with ioscan -fnC disk. is disk c5t0d1 detect by system. i think your device disk changes.

for recover please do:
mv /etc/lvmtab /etc/lvmtab.ori
vgscan -av

and check your lvmtab, do you have new lvmtab?

check with vgdisplay 0v vg


thanks

Yes agreed recreating the lvmtab should resolve your issue..

Hi Johnny,

Can u attach the syslog output ?? the last 100 lines atleast..we might get some more info from there..

After re-creating the /etc/lvmtab


Then re-activating the vg has fixed the problem.

#vgchange -a y

is it xp storage? you must check from xp side. need to do changes or not regarding changes wwn from your HBA.


thanks
