We use hszterm to send commands to some hsz's to start a mirror
operation. Sometimes we will get one mirror set fail to start. We see
error messages like:
%HSZterm: Send Diagnostic cam Status=0x5 (Cam subsystem is busy)
%hSZterm Send Diagnostic failed
device does not support Virtual terminal protocol.
My script does essentially this:
hszterm -b4 -t0 -l7 "set m_disk100 replace=disk110"
this will work for 5 out of the 6 disks I start mirror on, and
sometimes fail on the last one. When it fails I get 5 of these
messages. Does hszterm retry 5 times and the quit? HOw can I get
around this?
I assume the hszterm is failing to run, becasue the HSZ is still busy
doing the last mirror start.

HI Ron, sometimes it makes a difference which unit that you connect
through hszterm, try to pick a unit that is the least busy or a unit
that is not being effected by the hszterm command. That cam
message is typical with hszterm if the unit is experiencing cam
retries or errors, or sometimes if the hsz is really busy.

tell me more about the selection of unit to run hszterm on.
Can it be any unit and lun that is defined for the hsz, with the set
id=(0,1,2,3) command? Must it be a target for which a unit is defined,
or should it be a unit that is NOT defined.
In my case I have only units D0, D100 and D200 defined. I call my
hszterm commands like hszterm -b# -t0 -l7, so I am using LUN 7 on a
target which also has a unit.
WOuld it be better to call -b# -t4 -l7, so I refer to a target that
has no unit on it?
