HP-UX Adding a disk and file system extension in VXFS

Adding a disk and file system extension to VXFS

1.Presenting a  LUN to the host
Consider the name of the disc number  LUN command start 

 ioscan-m lun
*the number of the LUN appears in the 16-hexadecimal format

Look at the output of commands
vxdisk-o alldgs list

You should see our drive if it is not, then execute command
  vxdisk scandisks
and once again
  vxdisk-o alldgs list
Drive should already appear

2.Start  bdf and  look onto your mounted volume group and where we need to expand the space.

3. Add the disk to the appropriate disk group:
  vxdg-g dg_IDSusrsap adddisk dsk_IDSusrsap_D1 = disk476

4. Analyze how much space can be added. In this case, you must add the entire amount of dedicated LUN:

/ user / sbin / vxassist-g <name dg>-p maxgrow <name volume name> alloc = <drive name>

Get the result, for example 125728768

5.Adding space into the volume

/ etc / vx / bin / vxresize-g <name dg> <name vl> 125728768s alloc = <drive name>


Thats all check bdf to view result on your filesystem/
