A question which immediately popped into my mind is whether you locally labeled the tapes before starting to use them. Never assume that "pre-labeled" tapes are actually labeled, or labeled correctly. Initializing tapes on your drives and microcode levels can sometimes make a difference. >This is a new AIX server (TSM 5.2.2.4), latest ATAPE driver, new tape >drives/library ?

In a situation like this, isolation testing is in order. Remove the TSM factor by using tapeutil or similar utility to write and read back from selected tapes and try to narrow down the problem cause. (Relabel the tapes after this kind of exercise.) You may be able to establish an isolated test case for the CE to pursue, without TSM being in the mix for the CE to point at. Also, new hardware does not necessarily imply the most recent firmware: the hardware may have been installed with its factory-resident firmware - which can be old by the time the hardware finally makes it to a customer site - or the CE may have installed firmware from a tape which came with the shipment, which may not be as recent as what can be downloaded from the web. I would not turn off TapeAlert indiscrimately: that may be like removing the battery from that annoying smoke detector. Richard Sims
