Hello All, We have started experimenting with MOD-27 disks on a USP600 box. We have found that with DB2, response times have deteriorated significantly. We are seeing response times of more than 10ms on a fairly active disk. Disconnect time accounts for about 90% of the time. Cache disk ratio has gone down for these disks to less than 10%. HYPERPAV is active - IOSQ time is zero. zHPF is not enabled.
z/OS 1.9. DB2 V8. We have opened an issue with Hitachi. Has anyone else experienced this in a similar configuration?
