IBM iSeries
I have two iSeries machines both running v6r1. One is our production box (Model - E4A w/internal tape drive) and the other is a cold backup (Model 520 with external Transberg 3503-lto 4 tape drive).  I am trying to restore libraries from our production box to the backup. I can browse the the tape data on the old machine and see the libraries on there but when i try a rstlib I get the following error:
"device tap01 used for save or restore is damaged"
I can save library's from the backup machine to the external tape drive and restore them back to that same machine with no issue. Could the tape drives be using a different writing method/compression/block size?

iSeries, as400,

    Delete and recreate the Device Description on the machine that is giving you the problem.

    I deleted the device in wrkdevd and recreated it but still received the same error. I did notice that when i display the tape information the Block Length is different depending on which drive created the backup. The Block length on the external drive is 03276 and the internal is 262144. Could this be the problem?

    Yes, it could.

    First, we need the message ID rather than a description of the message text. Message text can come from anywhere and is only reliable for us if we know the message ID . Second, we need to know the tape drive device type on the E4A. It's not enough to know that it's "internal" since there are various kinds if internal drives. . It seems unlikely that block size is the problem in itself, though it could definitely be a symptom of the problem. A 'damaged' device description should not be indicated simply because of a block size difference; but block size difference could potentially be reported by a damaged device. . Tom

    When i get the "device is damaged error" the message id is: CPF3738. When i dspmsg QSYSOPR i see the message id:CPP6308 ("Tape device or library failed"). The tape drive is a 5746-001.

    First, I assume that "Transberg" was a typo for "Tandberg". But after that, I have been unable to find any IBM documentation that shows how or even if a Tandberg 3503-lto 4 tape drive can be used by a model 520 except through Tivoli Storage Manager (TSM). . If you aren't using TSM, do you have a link to appropriate specs, either at IBM or Tandberg? . Tom
