not a good idea

I would not recommend this. Once the 2 internal boot disks are mirrored, you should consider a 'set it and forget it policy'. If you absolutely must have bigger boot disks (not sure why) you need to rebuild the system and restore/migrate data. Hopefully you have a spare server around to build the new disks on. If your just looking to add more disk space cause your requirements are growing, just create a new disk group and start adding the disks to the disk group.

best practice for veritas is to mirror internals and NEVER put anything application related on the internal disks. Sometimes this cannot be helped and small things end up on boot drives. But everything else should go on external.

Of course this is just my opinion. I would not risk a system that is purring like a kitten.

I agree with this.

This is nonsense, you don't HAVE to do any such thing.

Excuse me? If you can find any Veritas document which states any such thing, can you please post a link? A general good practice is to keep the root disk mirrored and keep applications off it, there is no reason to tell someone they shouldn´t use internal disks for applications.

this is from my experience

This is from my experience. I recommend not using internals for major apps. Sometimes small things can creep up and need to go on internal, small things can be dismissed.

There is no doc. This is my experience. Putting things on internal disks can cause many issues, just one of which is performance issues. You dont want to put a major database on there. Of course, you have to strike a balance. I was merely stating that major apps should not really go on internals. I wont budge from this stance.

You dont have to do anything. The previous thread states all the info you need. I clearly stated that this is my opinion. Not sure why you are antagonizing me.

I was correcting misinformation which you posted, as is required of moderators on this site. Nothing more and nothing less.
