vgdisplay output and MCSG

Rick Garland — Thu, 07 Jul 2005 15:35:21 GMT

Hi all:

Working with HPUX 11.23, MCSG 11.16, ia64 systems.

Trying to write a script that uses the vgdisplay command. Trouble is I do not want the VGs that are not activated.

Tried using grep -v, parsing through the /etc/lvmtab file, etc.

Any hints?

Thanks

Well, if you don't want the scripts that are not activated then this is rather simple.

After getting your VG name from /etc/lvmtab then:

vgdisplay -v ${VGNAME} > /dev/null 2>&1
STAT=${?}
if [[ ${STAT} -eq 0 ]]
then # ok
vgdisplay -v ${VGNAME}
fi

the only solution I could find to this

vgdisplay | grep -v "not activated" | grep -v "Cannot display" > /tmp/file

and the output is the details from active groups only. error messages dump to screen. for some bizzare reason I could not get itto work with 2>/dev/null directive.
