Need help with an HACMP system 1

[sbrews]

I have a volume group on an HACMP system that needs more disk space added to it. Bringing HACMP (and all the various applications) down is not an option. I think I can get the space added and keep all of the HACMP resources happy by doing the following:

on node1:
shutdown oracle
extendvg oraclevg <devices>
synclvodm -P -v oraclevg
varyonvg -f oraclevg

on node2:
exportvg oraclevg
importvg -y oraclevg <device>
chdev -l <device> -a pv=yes (if pvid's need to be synchronized)
varyoffvg oraclevg (node 1 is the primary node)


I am still a newbie with HACMP stuff, so I am not sure if the above will work or cause me lots of grief. Any help would be appreciated.

hi ,

You can use HACMP DARE to do this i.e.

smitty hacmp

cluster system management

( the menus are the same as if you run smit and select storage option)

basically you don't have to stop your applications to do
that.

You have to make sure that the disk cam be seen from both servers.

if you cannot add the disk via smitty hacmp menu then
add disk to volume group using extendvg , an then use smit
hacmp , cluster management to increase/ create new filesystem , this procedure automatically varies the volume group on using the -b & u flags ( i.e.temporarily unlocks it) an the does an importvg -L on the remote node , and then varies the volume group on, this is all done via the smitty hacmp cluster managemnet menus)
