Hi Paul

First thing I'd look at is are the tape drives attached to the interface
card.

Otherwise a couple of things I'd wonder about are:
- DUPTAP/DUPMED from tape will be pretty much entirely streamed i.e. only
one read will happen at a time
- Tape alone is probably slower then DIsk/SSD (pasrticularly the SSDs)

What percentage used are the SSD"s

Anyone running Power7, SSD disk drives, LTO5 FH or HH, and either BRMS
AutoDup, DUPMEDBRM, or DUPTAP.
Also some knowledge on dynamic speed matching, data rates.
Is there any way of knowing what speed the tape drive is running at.
DUP, on the average, is taking 1 hour more than the save, starting to
cause issues.

Save rate averages 750 gb/hr. (1.9 gb save in 2 ½ hours)
DUP rate averages 600 gb/hr (1.9 gb DUP in 3 1/3 hours)

Good thought.

Also, forgot to mention that the user was not directly connected to the
LPAR B, but was passed through, STRPASTHR.

I did find what might be a common denominator, not sure if related.
At 12 noon, from a scheduled job, LPAR A does several (50 to 100)
SAVRSTOBJ from LPAR A to LPAR B.
These normally take a few seconds per object, longer if any locks.
Today, the first object took 5 minutes, then was successful.
I'm thinking some issue that connects the LPARS, maybe QSNADS, or
something else.

look for network problems. bad switch port, nic card on the PC,
cable(s) etc.

Steinmetz, Paul said the following on Mon, 7/22/2013 3:24 PM:

I had a single user (my manager / programmer) go input inhibited for 5
to 10 minutes, on all sessions.
LPAR was fine, I and others working fine.
Nothing in her joblogs, PAL, SAL, LIC log
Using MPG, I checked for locks, seizes, etc, I couldn't find anything.

Suggestions on where else to look or reasons for input inhibited culprit.

Thank You
