As a beginner as I am, I installed MQ (v6.0.2) on local filesystem (created directories as oppose to mount them) on an AIX platform. This is a new installation so there are no new objects created (no MQmgr, queues, channels, etc) - Now we need to mount the filesystem (/var/mqm/log and /var/mqm/errors) - Is this a "big/risky" job?

no, it's not big or risky.
Uninstall, remount the file systems, reinstall.

But I was hoping that we could mount the filesystem without any need to uninstall. Is that necessary?

No, it's not entirely necessary.
But when you mount a new filesystem on a particular location, like /var/mqm, then the old contents on the local disk are no longer available.
So you have to do something to save the old contents, mount the new file system, restore the old contents, unmount the file system, delete the old contents, and remount the new file system.

There is another (easier) way, to move the contents from directories /var/mqm/log and /var/mqm/errors:
- Mount the new volumes to a different mount mpoint (e. g. /var/mqm/log1 and /var/mqm/errors1).
- Move the contents to the new volumes with the commands "mv /var/mqm/log/* /var/mqm/log1" and "mv /var/mqm/errors/* /var/mqm/errors1".
- Re-mount the volumes to /var/mqm/log and /var/mqm/errors.
ALL QMgrs (if one is created) must be stopped, during the procedure above.
