HOW TO INCREASE A VOLUME IN VxVM CLUSTERED

1.-Check server master what is the master server
#vxdctl -c mode
mode: enabled: cluster active - SLAVE
master: linuxtest1

2.-Master Server
------------------
------------------
linuxtest1

2.1.-Slave Server

------------------

------------------

linuxtest2

3.-Connect to master server
---------------------------
---------------------------
ssh linuxtest1

4.-Check DG and FS before the change in our case we will increase data03 

#vxassist -g POE-dg  maxgrow data03
#vxassist -g POE-dg  maxsize data03


5.-Check Disks availables for adding in the Disk Group we discover the new disk sdat/sdau/sdav, that are in online status, however they are not part from any DG

#vxdisk -o alldgs list
DEVICE       TYPE            DISK         GROUP        STATUS
cciss/c0d0   auto:none       -            -            online invalid
sda          auto:cdsdisk    POE-54  POE-dg  online shared
sdaa         auto:cdsdisk    -            -            online
sdab         auto:cdsdisk    POE-56  POE-dg  online shared
sdac         auto:cdsdisk    -            -            online thinrclm
sdad         auto:cdsdisk    POE-57  POE-dg  online shared
sdae         auto:cdsdisk    -            -            online thinrclm
sdaf         auto:cdsdisk    POE-58  POE-dg  online shared
sdag         auto:cdsdisk    -            -            online
sdah         auto:cdsdisk    POE-59  POE-dg  online shared
sdai         auto:cdsdisk    -            -            online
sdaj         auto:cdsdisk    POE-60  POE-dg  online shared
sdak         auto:cdsdisk    -            -            online
sdal         auto:cdsdisk    POE-61  POE-dg  online shared
.

.

.

sdat         auto:cdsdisk    -            -            online
sdau         auto:cdsdisk    -            -            online
sdav         auto:cdsdisk    -            -            online


 

Include a new disk to disk group

Disk free
sdat         auto:cdsdisk    -            -            online
sdau         auto:cdsdisk    -            -            online
sdav         auto:cdsdisk    -            -            online

vxdg –g <group> adddisk <disk>=<device>

#vxdg -g POE-dg adddisk POE-66=sdat
#vxdg -g POE-dg adddisk POE-67=sdau
#vxdg -g POE-dg adddisk POE-68=sdav


Check maxgrow and max size of diskgroup and File System 

#vxassist -g POE-dg  maxgrow data03
#vxassist -g POE-dg  maxsize data03



Increase file system

#vxresize -g POE-dg data03 +30g
