mksysb backup restore with Tape Device

SAS and FC attached tape do not support boot because it needs atape device driver and atape device driver does not support boot.
SCSI attached tape does support boot because SCSI attached tape support AIX native tape device driver , so it is the only configuration that works with mksysb backup/restore.

    IBM has evaluated the priority of this enhancement proposal relative to other future product content and determined that this RFE will not be pursued for a future product release

    Also, this RFE is listed as AIX, but the missing piece is firmware support.

    This has been a concern for a long time. It is unlikely to see fibre tape drivers added to system firmware. The cost is high and the demand and funding are low.

    There are many alternative options:

    * boot from USB DVD that contains Atape, then restore from tape.
    * boot from USB memory stick, then restore from tape.
    * alt_disk_copy
    * mksysb to USB drive and restore
    * built a small LPAR and make it a NIM server.
    * attach mksysb ISO through VIO server.

    Best practice is to keep rootvg small, and do all data/datavg restores from the OS after BOS install.

    There are unsupported and unlicensed alternatives as well, but adding FC tape boot support to POWER firmware is in the opposite direction of 99% of the market.

    This is good request. I vote for enhancement of AIX native driver to support SAS and FC tape device.
