Therefore I re-post this topic today. z/VSE does not support concurrent microcode upgrade during a z/VSE system is active. Therefore I strongly recommend to shutdown the z/VSE system(s) for disk storage microcode upgrades, do the upgrade and re-ipl the z/VSE system. I would not plan the upgrade, if dependent z/VSE systems are still active. The following... [More]

Concurrent microcode upgrade with z/VSE
From time to time it is necessary to upgrade the microcode of your IBM Storage (ECKD/SCSI disk or tape). For ECKD storage I recommend to shutdown the z/VSE system before you upgrade the microcode. For Fibre-Channel-attached SCSI disks concurrent microcode upgrade is not supported. z/VSE with the latest service level supports concurrent microcode upgrade for IBM tape storage . Please consult your device documentation for details. We recommend to take the tape units offline (z/VSE OFFLINE command) prior to the microcode upgrade or use the next... [More]
