I recently had the same problem but on a z/OS 1.4 running on a z800 at a
client site.
They had a 3494 ATL with 3590 tapes and certain "J"s would take in excess
of 10 minutes to apparently come to load point even though one could look
inside and see the tape mounted etc. The problem only seeme

No, and if it was I would expect it to effect all cartridges equally.
This is a stand

Subject: Excessive 3590 load-to-ready time
The normal load-to-read
The normal load-to-ready time for tape cartridges on a 3590 B11 is 23
seconds according to the specs, and most of my cartridges do load in abou
t
that time. However, I have some cartridges that take over 5.5 minutes!
They are outwardly identical to those with normal load-to-ready times.
