emc_cfgmgr problem , aix host

Question

I have a emc_cfgmgr problem with one of my aix box ¿
I map & mask on Raid5 device to host, after that I run
/usr/lpp/EMC/Symmetrix/bin/emc_cfgmgr on host
It taking long time and checking all hdisks in the host I have 2 volume groups

County1/root:/>lsdev ¿Cc disk

county1/root: / > lsvg -p emcvg
0516-010 : Volume group must be varied on; use varyonvg command.

Because this host is a HACMP cluster of production server so the emcvg must be varyoff

Emc_cfgmgr checking all disks saying the hdisks which have EMC Symmetrix FCP Disk TimeFinder
State are in undetermined state and checking some other things and came back to state of checking those
Disk time finder devices and saying same msg and still running for past 30 mins

This county1 host is a HACMP cluster and is a mirror of county2 server and my colleague said HACMP is not active rightnow, And SRDF is running on county2 continuously like a loop process ..we have a script provided by the EMC for SRDF , so in the log file ( /var/symapi/log/ symapi-20071228.log ) I seen the processes of synchronize , split , establish , suspend , synchronize and split Are running like loop process and I run symmir command for county2 device group I found the state of devices is keep on changing like syncinprog, synchronize , split like that from time to time with in span of minutes so is this is a reason for emc_cfgmgr saying hdisks are in undetermined state on county1 ..I assume ¿

i would try to run emc_cfgmgr when BCVs are in Split state.

rawstorage · Answer

If you are attempting to mount the BCV's at the R2 side you should first of all stop your replication script after a complete cycle.

Dynamox is right you should run the cfg mgr when the BCV's are in a split state.

If the emc_cfgmgr is running during the middle of a cycle the device state will be changing, the BCV will become not ready when it is in sync in progress and will change to RW when it is split. This could be confusing for the emc_cfgmgr script if the replication process is running.

Before stopping your script you should also ensure you know how to restart it and what state everything needs to be in before kicking off.
