This is a zOS TSM 4.2.3.2 server. The client server is AIX 4.3 with TSM client 4.2.3.0
We had a recent hardware failure/disaster which resulted in a complete wipe of 250GB+ of storage on an AIX 4.3 system. To complicate matters, this is one of our email system, with 22-MILLION files comprising the 250GB. So, we start the *BIG* restore. To put it quaintly, restore performance sucks. We are averaging .5GB per hour. At this rate, it will take 15-20 DAYS ! I have gone through the "TSM Performance Tuning" guide, to no avail. I had pretty much done everything the book suggests, long ago, with the exception of pagefixing storage for the VSAM/BSAM reads. Even checked its recommendations for the AIX system for things like TCPIP settings, etc. The AIX system is hardly breathing hard, when it comes to CPU utilization. What can I look at to do anything I can to speed things up ? Can I run multiple restores of different filesystems ?
