Extension of file system in HACMP

1          Extension of file system in HACMP

 CSPOC can be used if it is a shred filesystem .

Step 1 When free space available

 

Check the volume group if free PPs are available then extend the filesystem

Online by chfs command on primary node

 

Chfs –a size=+---M filesystem name  ( extend filesystem )

 

On primary node do varyonvg –b –u  vgname ( open lock )

 

On seconday do importvg –L vgname vpathname  (volume group in learn mode)

 

On primary do varyonvg vgname ( close lock )

 

Step 2 When free space not available

 

If PPs are not available check for free luns on primary node

Run cfgmgr –Sv command

 

Check on server whether free luns are available

If not, Assign ticket to Storage Team with log comment

For necessary luns allocation.Once luns are assigned on system check for primary and

Secondary luns

Check pvid are same on primary and secondary node, you need to bring pvid from primary to secondary, you can do that by creating testvg on primary and importing the same on secondary. Once both pvids match , then use extendvg to add new luns to volumegroup.

Extendvg vgname vpathname

 

Remaining process is same as in step 1 above.
