How to monitor the status of the mirrorvg in aix?
If
you run the mirrorvg command, it will lock the rootvg volume group and also you
could not able to identify the status of the mirrorvg and you could not able
guess how long it will take to complete the sync process.
But
using below, you could able to identify the status of the sync, i mean you can
able to identify how many stale pp still there to sync up.
METHOD 1:
Mirror
the rootvg Volume Group by executing below command:
#mirrorvg
–S rootvg (The ‘-S’ option (Uppercase ‘S’) is for Background sync)
Type
the following command to find out whether the disks are synchronized or not
#lsvg
rootvg|grep STALE
STALE
PVs: 1 STALE PPs: 34
Note:
Wait until the ‘STALE PPs’ becomes 0 (zero), the synchronization time depends
on the size of the hard disk
METHOD2:
mirrorvg -s rootvg hdisk1 ('s' is in lower case)
Mirroring
complete immediately after executing the below command with -s flag, but we
have to execute the syncvg command by ourself.
syncvg
-P 4 -v rootvg
-P
flag is for number of threads that should be started to perform the sync
process. it can not lock the volume group. so we can track the mirroring by
another window.
Take
the another window:
lsvg
rootvg | grep STALE | xargs
STALE
PVs: 1 STALE PPs: 95
Note: Wait until the ‘STALE PPs’ becomes 0 (zero), the synchronization time depends on the size of the hard disk
