291.0. "Empty slot and MRU (LOAD failed)" by PRSSOS::MENICACCI () Mon Feb 24 1997 02:33
Hi,
here is a log from a customer using MRU V1.1 with a TZ867.
Summary : loading an empty slot results in making the whole drive unusable.

============================================================
The only solution is then to reset (OFF/ON) the TZ.
The workaround is to : 1) fill every slot with media
2) not loading an empty slot
============================================================
Is that intended behaviour ?
TZ867 firmware was version 4308 _ I ask to upgrade to 4318 or later.

| I hate to say it this way, but ask the drive vendor... MRU
relies on drives handling SCSI-2 medium changer commands in
a reasonable way. If they don't there is nothing we can
do about it. If the drive isn't running the most current
firmware an upgrade would be wise.
Tape hardware issues typically get discussed in STKHLM::MAGTAPE.
