☐

MPS A: Note down the timestamp in log.

Run the following command :

$ date

9.

☐

MPS A: Check that drbd syncing is complete. If not, then wait for drbd to sync

Note: If DRBD is still syncing, run the DRBD status command periodically to check until both ELAPs get synced.

Run the following command to display DRBD status.:


# drbdadm status all 
Expected status:  
Role: Primary/Secondary 
Disk: UpToDate/UpToDate

Example: 

$ drbdadm status all drbd0 role:Primary   disk:UpToDate 
  Devloan04 role:Secondary     peer-disk:UpToDate

If drbd is still syncing, you will see some output in percentage which shows that drbd is getting synced. Wait until it syncs completely till 100% and comes as Primary/UpToDate and Secondary/UpToDate. 


# drbdadm status all drbd0 role:Primary   disk:UpToDate 
  Devloan04 role:Secondary 
    replication:SyncSource peer-disk:Inconsistent

done:66.44

10.

☐

MPS A and MPS B: Check

the hastatus on both the nodes.

Check the hastatus on both the nodes. MPS A should be ACTIVE.
# hastatus 
ACTIVE

MPS B should be STANDBY. 

# hastatus 
STANDBY

If hastatus for MPS B shows as “UNINITIALIZED "INHIBITED"”, then run the below command to make it STANDBY.

 # /usr/TKLC/plat/sbin/hafailover --noinhibit

Example:

 
[root@Crete-B ~]# /usr/TKLC/plat/sbin/hafailover -noinhibit 
[root@Crete-B ~]# hastatus UNINITIALIZED 
[root@Crete-B ~]# hastatus 
STANDBY 
[root@Crete-B ~]#

Make sure that delay and offset is zero. If delay and offset is not zero, run the below commands else skip the below commands. 

# systemctl stop chronyd 
# systemctl start chronyd
# systemctl enable chronyd
# chronyc makestep

Run the below command to note the current timestamp on the server:

# date

12.

☐

MPS A and MPS B:

Reboot both MPS A and MPS B servers once after drbd is synced.

Reboot both MPS A and MPS B servers using below command.:

# reboot

13.

☐

MPS A and MPS B: If any core files were formed during the upgrade MTC window, delete them.

Delete the core files that were formed during the upgrade maintenance window using below command. These core files are one time.

# rm /var/TKLC/core/<core file name>

For example: 

# rm /var/TKLC/core/core.gs.10084* 
rm: remove regular file '/var/TKLC/core/core.gs.10084'? Y 
rm: remove regular file '/var/TKLC/core/core.gs.10084.bt'? Y

This procedure is complete!
