Hi all, I'm moving a couple of apps - SAP/DB2 and an oracle data warehouse - from an RS6000 SP cluster on to a couple of brand spankin' new P690s, and at the same time moving to a new datacentre. It's just across the road but it might as well be on the moon.
1. The SP cluster has a fast internal network, but only 10MBit external. 2. There is a 3494 connected to the TSM server on both sites. 4 drives on old site and 2 drives on new 3. The move is time limited. 4. The SP must not be disturbed for 6 weeks after the move just in case we want to go back. One approach is to back up to TSM, backup the TSM database, remove the tapes needed, bring up TSM at the new site and restore. Ok, but complex and messy, and hard to do in small chunks (for the test migrations along the way). Second approach - export node data, and import to new TSM server then restore. Export/import operations are single threaded and tape to tape therefore slow. The sap DB alone is 350GB, so I can't make this work in a reasonable timeframe (backup/export/transport/import/restore) Third approach - detach a drive from TSM. Run a backup utility on the source machine to either stdout or a named pipe depending on the utility, then read from this across the SP switch to the TSM node with rsh and from there to tape. Testing has revealed that this will work and be both simple and fast- but, I need a utility that is smart enough to recognize end of tape and the 3494 autoloader mode and load the next tape automatically. I've tried the pax and aix backup utilities with no success. Can anyone point me at a utility that can do this or suggest a different approach to the problem? Also I'd love some real world information on how to set up the 3494 autoloader mode and use it from AIX, just to be sure that I've got that bit right.
