Rezoned EVA not lvmtab out of date
Our EVA team recreated the fabric on our eva.
we are running hp-ux 11.31 server has 2 hba's
(alsmp2):/:# vgdisplay /dev/vg05
vgdisplay: Warning: couldn't query physical volume "/dev/dsk/c6t0d4":
The specified path does not correspond to physical volume attached to
this volume group
and "/dev/dsk/c2t0d4":
and "/dev/dsk/c8t0d4":
looking at lvmtab all links failed except /dev/dsk/c4t0d4
thus I tried
(alsmp2):/:# ioscan -m dsf /dev/dsk/c4t0d4
Persistent DSF Legacy DSF(s)
========================================
/dev/disk/disk28 /dev/dsk/c4t0d4
(alsmp2):/:# ioscan -m dsf /dev/disk/disk28
Persistent DSF Legacy DSF(s)
========================================
/dev/disk/disk28 /dev/dsk/c4t0d4
/dev/dsk/c24t0d4
/dev/dsk/c16t0d4
/dev/dsk/c20t0d4
Now can I run vgreduce to clear the redundant links as only one is still working.
Then can I run vgextend with the new links I get above?
Also can I do it on a live system as the old links do not work anyway?
Please the exact command would help a stressed administrator.
Thanks
Kevin

Re: Rezoned EVA not lvmtab out of date
The vgscan command allows the re-creation of the /etc/lvmtab file and possibly the associated volume group device files. This command should be run only in the event of a catastrophic error such as the deletion of the /etc/lvmtab file or the mismatch of names of the physical volumes in the /etc/lvmtab file to the actual physical volume path configuration.
