Case 1: Storage Engineer adds new Lun
Once you get LUN id's from Storage team, gather below info:
Server | Pseudo name | ID | Size | Disk name |
server 1 | emcpower62 | 15F9 | 674.31GB | emcpower62a |
emcpower63 | 0B2A | 674.31GB | emcpower63a | |
emcpower64 | 0B20 | 674.31GB | emcpower64a | |
server 2 | emcpower63 | 15F9 | 674.31GB | emcpower63a |
emcpower64 | 0B2A | 674.31GB | emcpower64a | |
emcpower65 | 0B20 | 674.31GB | emcpower65a | |
Use below commands to obtain the above info:
powermt display dev=all
echo | format | grep <diskname>
Activity:
1. Take backup of below o/p on both primary and secondary node.
a. powermt display dev=all
b. vxprint -rth
2. Check the current status of new disks (visible in primary)
[root@server1]
# vxdisk list | egrep "emcpower62|emcpower63|emcpower64"
DEVICE TYPE DISK GROUP STATUS
emcpower62s2 auto - - nolabel
emcpower63s2 auto - - nolabel
emcpower64s2 auto - - nolabel
3. Freeze the service group
[root@server1]
# hagrp -freeze server-sg -persistent
[root@server1]
# hastatus -sum
-- SYSTEM STATE
-- System State Frozen
A server1 RUNNING 0
A server2 RUNNING 0
-- GROUP STATE
-- Group System Probed AutoDisabled State
B ClusterService server1 Y N OFFLINE
B ClusterService server2 Y N ONLINE
B server-sg server1 Y N ONLINE
B server-sg server2 Y N OFFLINE
B oracle-sg server1 Y N OFFLINE
B oracle-sg server2 Y N ONLINE
-- GROUPS FROZEN
-- Group
C server-sg
-- RESOURCES DISABLED

H server-sg Share cprdata-share
H server-sg Share cprmnt-share
H server-sg Share cprwin-share
H server-sg Zone linkvpr-Zn
4. Identify which disk group /var/data is part of to increase
[root@server1]
# df -h /var/data
Filesystem size used avail capacity Mounted on
/dev/vx/dsk/datadg/datavol 15T 12T 2.3T 85% /var/data
5. Now Initialize the device and make it online in veritas control
[root@server1]
# vxdisk init emcpower62 format=cdsdisk
[root@server1]
# vxdisk init emcpower63 format=cdsdisk
[root@server1]
# vxdisk init emcpower64 format=cdsdisk
[root@server1]
# vxdisk list | egrep "emcpower62|emcpower63|emcpower64"
DEVICE TYPE DISK GROUP STATUS
emcpower62s2 auto:cdsdisk - - online
emcpower63s2 auto:cdsdisk - - online
emcpower64s2 auto:cdsdisk - - online
6. Add new devices to datadgs
6.1 Identify the disk name that could be assigned to new device here we can see last disk name is datadg20.
[root@server1]
# vxdisk -o alldgs list |grep datadg
DEVICE TYPE DISK GROUP STATUS

emcpower64s2 auto:cdsdisk datadg23 datadg online
emcpower80s2 auto:cdsdisk datadg11 datadg online
7. Now check the max amount of disk space can be increased from disk group
[root@server1]
# vxassist -g datadg maxsize
Maximum volume size: 4282972160 (2091295Mb)
8. Increase the volume and filesystem size using output from previous command
[root@server1]
# /etc/vx/bin/vxresize -F vxfs -g datadg datavol +4282972160
9. Verify /var/data filesystem size is increased and capture screenshot for proof
[root@server1]
# df -kh /var/data/
Filesystem size used avail capacity Mounted on
/dev/vx/dsk/datadg/datavol
17T 12T 4.2T 75% /var/data
10. Unfreeze the service group server-sg in server1 (As this SG is online only in server1)
[root@server1]
# hagrp -unfreeze server-sg -persistent
[root@server1]
# hastatus -sum
-- SYSTEM STATE
-- System State Frozen
A server1 RUNNING 0
A server2 RUNNING 0
-- GROUP STATE
-- Group System Probed AutoDisabled State
B ClusterService server1 Y N OFFLINE
B ClusterService server2 Y N ONLINE
B server-sg server1 Y N ONLINE
B server-sg server2 Y N OFFLINE
B oracle-sg server1 Y N OFFLINE
B oracle-sg server2 Y N ONLINE
11. Login to secondary node to discover new disks so added to the dgs
[root@server2]

e.g.
First increase the size of the disk in vxvm:
