Hi Friends,

Any idea what is command equivalent to increasing the File System using smit hacmp? And does increasing the File System by using smit hacmp ( on cluster based system) also syncronize the both the Primary and Failover systems Files system. If yes then what command it uses for synchronizing....?

Thanks in Advance,

yes, when you use C-SPOC utilites to create/modify cluster's shared VG/LV/FS it updates all corresponding cluster nodes.

smitty cl_lvm
or direct smity fast path to c-spoc shared fs shows/change:

smitty cl_chjfs2 #for jfs2 type filesystems
smitty cl_chjfs #for jfs type filesystems

You can find how the command is constructed in /smit.log (you need to run is first from smit log),

or you can read in /usr/es/sbin/cluster/cspoc/smitlvm script how it works - you will find there that '-10' option invokes later /usr/es/sbin/cluster/cspoc/cli_chfs (for filesystems changes operations)

-10) RGNAME=$2
NAME=$3
shift 3
cl_chfs -cspoc "-g $RGNAME" $* $NAME
;;
eg.
/usr/es/sbin/cluster/cspoc/smitlvm -10 'A_CL_RGRP' '/asharedfs' -a size='22020096'.

RGNAME=$2=A_CL_RGRP (cluster resource group where the shared VG/FS is configured in)
NAME=$3='/asharedfs'
$*=the rest (shift 3)="-a size='22020096'" #for above example

will set filesystem size to 22020096 512byte blocks.

correction:

instead of:
You can find how the command is constructed in /smit.log (you need to run is first from smit log),
shoud be:
You can find how the command is constructed in /smit.script (you need fist change filesystem from smitty to have the command synthax 'recorded' in /smit.script)
