After reading the above link, it appears that SnapManager integration w/ PM only works for Backups & Remote Backups, it doesn't work for mirror policies. Does anyone know if there's a way around this? Or when this feature will be available?
I have several protection policies that do Backup > Then Mirror. I thought since the first step of the policy was "Backup" we could select this protection policy, but when I got into SM it ONLY lists the backup ONLY policices, it doesn't list any policies that have a mirror step in them.

There are couple of reasons as to why only Backup/Remote Backup policy was allowed.
Non-Disruptive Lun restore is supported only for SnapVault relationships.
As Backup/Remote Backup policies allow you only to create SnapVault relationships.they are allowed.
Also the work around would be to change the policy from Protection manager for the dataset.
though i am not sure if there is any impact from the snapmanagers.
you might have to test to see if there is any impact.

I assume this NOW page talks to SMSQL. In SMO, all the protection policies are visible and usable in the 'Profile-create' wizard. However, as Adai
has mentioned, the LUN restore may be disruptive for mirror related policies, in which case you might need to bring DB instance down to mounted state.

I have the same question. Presently, my customer uses Snapmanager Exchange to backup and then kick off snapmirror replication. If they were to purchase Protection manager would they still be able to do the exact same thing via PM (i.e. backup with SME and then immediately kick off a snapmirror replication)? If not, how would this be accomplished? 2 diferent policies?

At present SME user will not be able to do snapmirror via PM policies, SME supports "Back Up" and "Remote Backup" only policies via PM. SME supports snapmirror without going through PM interfaces, please refer to SME admin guide.

Hmm. I don't really see the benefit of PM and SME integration if PM cannot support a backup and replication policy. I can do both of those through SME today without PM. Basically, you're saying to use PM policy for the backup portion and ensure I check the snapmirror button when i create the job in SME? Kinda defeats the single-pane of glass value-add of PM IMO.
If I was doing SME archiving via SnapVault I can clearly see how PM would be of value. But for just backup and snapmirror replication I cannot see the value of the integration.

Is this documented anywhere? Seems so much easier to just use SME alone and create one job to backup and snapmirror. I didn't know you could create datasets within SME. I thought that was only possible in PM.

I will not recommend switching SME dataset policy from "Backup" or "Remote Backup only" to "Backup then Mirror" using PM. This is NOT a tested functionality in SME, moreover transactional log data will not be propagted to mirror as soon as logs are snapshoted at the primary storage by SME.
