that is OK. That is binary file and not ascii.
file /etc/lvmtab
The printable chars can be seen with strings command.

strings /etc/lvmtab

Hi,

This is quite usual. What hard disk status you wish to see?

#diskinfo -v /dev/rdsk/cxtydz

Or

#vgdisplay -v /dev/vgxx

The VG should be activated on that node to give output of vdisplay.

HTH,
Devender

Hi ,
If your vgdisplay is showing correct informations, then it is ok.

strings will print printable characters from a binary file..

Regards,

Shameer

Hi:

'strings' does the best it can to display a binary file in readable characters.

The '/etc/lvmtab' file is a binary file and actually consists of the VGID (volume group identifier), the volume group name, and the physical device file names for each volume group.

The "junk" characters you are seeing are actually the best representation that 'strings' can make of the VGID.

This is normal and no cause for concern.

Regards!

Hi;

Execute the following command.

#cmviewcl

To view the Cluster_name, node and package name.
#strings /etc/lvmtab
#cat /etc/lvmpvg
#diskinfo
#vgdisplay -v |more
Try all the command in all the cluster boxes.
Also have a look in .
#cd /etc/cmcluster/package_name
search for .cntl file (it may be in some other format.

Try this.. Hope this will help u to resolve ur issue.

Cheers

strings /etc/lvmtab |grep dsk
pvdisplay -v diskinfo -v vgdisplay -v
