HPUX :EXTENDING THE FILE SYSTEM, ADDITION OF NEW PV (CDISK) OR EXTENDING THE VG IN CLUSTER

Note :Once we have created cDSFs for the cluster, HP-UX automatically creates new cDSFs when

you add shared storage.

otherwise we have to run

#insf

#cmsetdsfgroup -n «PrimaryNode»  -n «FailoverNode»

It will convert all new disks in Cdisk.

2.pvcreate with newly added cluster wide disk.

#pvcreate  newdisk

3. extend the VG

#vgextend  vgname  newlyaddeddisk

#lvextend -L +newsizeM lvname

#fsadm -F vxfs filesyste

#vgexport -p -v -s -m vgname.map /dev/vgname

#scp vgname.map nodeB:/etc/cmcluster/packageA

#edit the package conf file , if we added in LV/File system.

#cmcheckconf -v -P packageA.conf

#cmappyconf -P packageA.conf

NodeB

#vgexport /dev/vgname

#vgimport -m vgname.map -s -v -C /dev/vgname

Need to add –C switch for cluster device file system
