How to migrate 2TB from Attached Storage Array to Internal Disks
Forgive me for my ignorance I'm a DBA asked to step in for a Unix Administrator who has moved on. We are looking at decommissioning the Fibre Channel attached SAN and I have been asked to look at purchasing and migrating the data to internal disks. The physical server is a Sun T2 running on Sparc. On which we have 2 zones running. I believe there are 4 disks in the server. 2 mirrored for root the other 2 striped for database files. We are using ZFS file system zpools for each file system sitting on top of each of the attached LUNS.
I was hoping someone could advise what the best solution for migrating almost 2 TB of data from the SAN to internal disks is. The volumes are mostly made up of Database Files, Archive Logs, RMAN backups and the EBS 12.1 application software. We aren't using Oracle ASM for the database but introducing it may be an option if it can be justified. Minimizing down time would be a bonus but this isn't a 24-7, 365 days system. In fact we don't officially support usage over weekends. nevertheless the server does hold critical financial data which the business couldn't afford
