To provide optimal security to different types of volumes by changing the user and group properties, run the following:

vxedit [-dfGpPrsvV ] [-e pattern] [-g diskgroup] cc /search/replace/ [gp] [name...]

1. Verify the current user and group id,  using the following command:

  # vxprint -htmg

For rootdisk7vol,  for instance under rootdg disk group, the following output will show;

vol    rootdisk7vol
       tutil0="
       tutil1="
       tutil2="
       kstate=ENABLED
       r_all=GEN_DET_SPARSE
       r_some=GEN_DET_SPARSE
       w_all=GEN_DET_SPARSE
       w_some=GEN_DET_SPARSE
       lasterr=0
       use_type=gen
       fstype="
       comment="
       putil0="
       putil1="
       putil2="
       state="ACTIVE
       writeback=on
       writecopy=off
       specify_writecopy=off
       logging=off
       has_logs=off      
       devopen=off
       move=off
       log_serial_lo=0
       log_serial_hi=0
       node_bdev=216/6
       node_cdev=216/6
       iosize=512
       pl_num=1
       pref_name=
       start_opts="
       read_pol=ROUND
       current_read_pol=ROUND
       minor=6
       user=root
       group=root
       mode=0600
       log_type=REGION

2. Modify the user and group ID,  using the following command:
   
# vxedit -g set user="" group=""

For instance, to change the owner for rootdisk7vol to "admin" in rootdg disk group, use the following command:

# vxedit -g rootdg set user=admin group=admin rootdisk7vol

3. To verify your work use the following steps from step 1:

# vxprint -htmg

vol    rootdisk7vol
       tutil0="
       tutil1="
       tutil2="
       kstate=ENABLED
       r_all=GEN_DET_SPARSE
       r_some=GEN_DET_SPARSE
       w_all=GEN_DET_SPARSE
       w_some=GEN_DET_SPARSE
       lasterr=0
       use_type=gen
       fstype="
       comment="
       putil0="
       putil1="
       putil2="
       state="ACTIVE
       writeback=on
       writecopy=off
       specify_writecopy=off
       logging=off
       has_logs=off      
       devopen=off
       move=off
       log_serial_lo=0
       log_serial_hi=0
       node_bdev=216/6
       node_cdev=216/6
       iosize=512
       pl_num=1
       pref_name=
       start_opts="
       read_pol=ROUND
       current_read_pol=ROUND
       minor=6
       user=admin
       group=admin
       mode=0600
       log_type=REGION
