vgdisplay showing errors
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
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.

Re: vgdisplay showing errors
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..

Re: vgdisplay showing errors
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
