We have been trying to upgrade the LMU/LCU on our STK9310 ( PowderHorn ) ATL to support STK9840D tape drives. We currently have microcode level 1.9.26 on the LMU's and we have microcode level 4.2.04 on the LCU's.
For the 2nd weekend we attempted to upgrade the microcode level to 1.9.74 on the LMU's and 4.4.08 on the LCU's. The installation/activation of the microcode appears to successful. The LMU's activate successfully, the LSM's activate successfully and all of our tape drives work. We are able to mount/dismount tape cartridges in all of our tape drives. However when we attempt to any type of CAP processing, 'ejects' or 'enters' something goes very wrong and the entire SILO ( the entire ACS ) appears to become unresponsive because the STK HSC host software reports that the ACS is disconnected. Last weekend we were running on the 'new' LMU/LCU microcode for more than 90 minutes before we attempted to perform a CAP 'enter'. The robotics appeared to 'read' 11 tape cartridges before we recieved the "ACS Disconnected" message on the z/OS consoles. Yesterday we were running for about 30 minutes before we attempted to eject 1 3490 tape cartridge. The robot had retrieved the cartridge from its storage cell, moved it to the CAP cell before we received the "ACS Disconnected" message on the z/OS consoles. We have engaged STK software support who says they have not encountered any problems with this level of microcode. They are attempting to analyze some HSC 'trace' data we captured yesterday when the problem occrred. I was wondering if anyone has STK9840D tape drives installed in a STK9310 ( PowderHorn ) ATL ( not an SL8500 ) and if so, would you be willing to share with me your LMU/LCU microcode levels and if you do any CAP processing. Thank you in advance for any help you can give us.
