The AVE limits the amount of space allocated during the installation. If you are in touch with EMC support they can advice how you can get a larger chunk of the disk recognized by Avamar.
I hope this helps
Before While I was configuring an ave for replication, it's usable disk size decreased to 500 gb to 340. I contacted emc support and they said it was an expected issue for read only servers.They said they are incresing capacity to default after their health check. I mean, there isn' t any read only server now but server disk status decreased again.
If I were you I would contact the support team and reference the case for the health check where the readonly limit was supposed to have been lifted.
It's possible that the parameter may not have got changed after the health check so would be a good idea to get that double checked..
This really needs to be checked over by support so that they can ensure that all is well before making the change. If you can let me know the SR number I'll contact the case owner for you. Alternatively, try calling dispatch on : +1-877-534-2867 and asking for a response request for the SR.
