/etc/lvmtab

My lvmtab is completely hosed. How do I create a new one?

Try this:

# mv /etc/lvmtab /etc/lvmtab.old
# vgscan -a

Couldn't stat physical volume "dev/dsk/c0t9d0":
Invalid argument
Physical Volume "/dev/dsk/c1t2d0" contains no LVM information

The Volume Group /dev/vg03/group was not matched with any Physical Volumes.

Hi Stuart,

Make sure you remove the old file or at least move it out of /etc. vgscan will refer to the file & use it as a template therefore recreating the same problems you had before.

Rgds,
Jeff

Did that. Got the same results.

What is your definition of a hosed lvmtab? You are using "more" on a binary file that happens to contain some string data. It's always (very statistically speaking, highly probable) that lvmtab will contain non-ASCII characters. A better technique is "strings /etc/lvmtab" to produce much more human readable text although occasionally some seemingly strange characters will appear because strings looks for sequences of 3 or more printable ASCII characters in secession for output.

The /etc/lvmtab file was not meant to be read directly with the pg or more commnand. Would you please post the results of:

# strings /etc/lvmtab

Then maybe we can get a hint as to the problem you are having.

# strings lvmtab
/dev/vg00
/dev/dsk/c0t5d0
/dev/vg01
/dev/dsk/c0t8d0
/dev/vgOra9
/dev/dsk/c1t5d0

It doesn't show my other disk with vg03.

If you notice the error message in one of your replies, vgscan states that it could not stat physical volume /dev/dsk/c0t9d0. That indicates to me that the disk is dead.

Do an 'ioscan -fnC disk' and see if c0t9d0 shows up as NO_HW. If so, it is definitely dead and needs to be replaced.

this here is your dead ringer :

disk 2 8/4.9.0 sdisk NO_HW DEVICE SEAGATE ST39175LC

NO_HW, hence, the disk hardware is bad.

Yep, it appears you have got a quite dead 9GB at c0t9d0. If you have an HP support contract, call HP and have them replace it.
