Operating Systems AIX Unable to extend volume group(VG) Post 302887088 by ibmtech on Wednesday 5th of February 2014 02:45:02 PM

You don't have to unmount file systems or varyoffvg.

Are you 100% positive the storage admin have increased the LUN size?
Code:
run 

bootinfo -s hdisk2 --> what is the size

cfgmgr -i hdisk

bootinfo -s hdisk2 --> what is the size(if SAN admin increased the LUN size you should see it here)

Now,
lsvg oravg | grep 'TOTAL PPs'

chvg -g oravg

lsvg oravg | grep 'TOTAL PPs' --> You should see the PP increase here.

You cannot extend a hdisk, which is already assigned to a VG.

DO NOT use extendvg command

1st figure out the LUN is increased in size or not.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
