File system references are maintained at the package level.  Do you know which package you want to modify?

Failover-type packages list file systems in either the legacy package control script, or modular package configuration file.  To learn which style your package uses, run:
$ cmviewcl -v -f line | grep style

Depending on the style, modify the associated file, adding lines for the file system, and include mount options.

If the underlying volume (LVM or (VxVM) has not yet been created, create it on the system where the VG or DG is currently active, then newfs the file system in the volume.  After doing so, the other node(s) need to get a /dev/<vgname>/<new_lvol> file for this new volume.   Use the vgexport/vgimport discussed in other threads to do this.

Hi,

Your requirement is not specific to any problem so sharing the normal command line steps for new FS creaion and modification of cluster configuration for the same.

Hope that this will help you.

Physical Volume Create On Volume Group : sample VG VG01

  1. pvcreate -f /dev/rdsk/cxtxdx
  2. mkdir /dev/vg01
  3. mknod /dev/vg01/group c 64 0x010000
  4. vgcreate /dev/vg01 /dev/dsk/cxtxdx
  5. lvcreate -n vg_name -L <lv_size >/dev/vg01
  6. newfs -f vxfs /dev/vg01/r_lv_name
  7. vgexport -p -s -m /tmp/vg01.map /dev/vg01
  8. rcp /tmp/vg01.map node2:/tmp/vg01.map
on node2
  9. mkdir /dev/vg01
 10. mknod /dev/vg01/group c 64 0x010000
 11. vimport -s -m /tmp/vg01.map /dev/vg01 /dev/dsk/cxtxdx

Clustering Steps :

  1. edit .rhosts file entries of both node
  2. cd /etc/cmcluster
  3. cmquerycl -C cmclconf.ascii -n node1 -n node2
  4. edit /etc/cmcluster/cmclconf.ascii (enter cluster name & parameter)
  5. ftp /etc/cmcluster/cmclconf.ascii  (to another node)
  6. vgchange -a y /dev/vg01            (activate volume group)
  7. cmcheckconf -C cmclconf.ascii
  8. cmapplyconf -C cmclconf.ascii
  9. cmcruncl
 10. cmviewcl -v

Hi

Can you explain the senario ,Is it was in cluster Environment ? How many vg's are there
