BTW: 3494 Library ID is not hardcoded in metal. It can be easily changed
from operator panel (although requires Service logon). It is quick and
easy. Is it the option for you to chaneg LIB ID instead of IODF ?
BTW2: AFAIR It is not required to code LIB ID in IODF at all. Having ID
is more convenient, but not required. I don't remmeber details, I always
code the ID.
John,
As Radoslaw hinted at, there's no need to code Library ID and Libport
these days...so one simple solution is to remove them altogether. It
will then work at home and at DR. AFAIK it works this way for all
current library/VTS devices.
Z/OS will query the device at IPL time to get the id/libport (you can
see it with DS QT,xxxx,RDC on 2nd line of hex I think). If the library
is not available at IPL (as might be the case at DR) then you will need
to do the following..
1) Vary online all devices. They will fail to come online with a variant
of msg IEA437I...ACTIVATE REQUIRED. You have try to bring them online,
even though they will fail.
2) Issue a SOFT activate for the current IODF, to rebuild EDT.
3) Vary Devices online again
Ps Although you can change the library ID on the 3494, Libports are
fixed based hw config of the library. So if the Hw configs at DR are
different, changing just the library device wont suffice. Also changing
these ids and serial numbers in the library will probably require a
re-teach or reset of the whole library.
