The recent talk about srdf and dr reminded me of our situation Layout: - 2 Datacenters with a routed SAN (90 miles a part) - TSM DB is on DMX that is setup with SRDF in sync mode to the remote site. - The DMX luns are assigned to the AIX host, and formated with JFS2. - The log volume does share one of the luns with part of the DB. (I'm not sure if this is a big deal or not) - VTL's and library managers at both sites. Primary pools at one site, copypools at the other.
I tested an srdf split, while TSM was running, and attempted to bring TSM up at the remote site. It was not successfull, and a DB restore would have been required. We re-established and split again with TSM down. This time it worked fine. When this was originally implemented, the project owners claimed that SRDF was a supported solution. After this test, I called IBM to verify it, and support said the only form of DR that is supported is a database restore. Questions: Is there any trick to get this working right? Do I have to have the log on a separate lun? maybe different srdf group? Should I be running this in Async mode? I think the 90 mile separation prevents me from using TSM to mirror the volumes. This would introduce a big performance hit, right ? Regards, Shawn This message and any attachments (the "message") is intended solely for the addressees and is confidential.
