ERB464I

Explanation
An attempt by RMF™ to
obtain device counters for cu_type failed. The
reason for the failure is indicated by the return code as described
below.

System action
RMF writes
an SMF type 74-5 problem record with status code R745CSC=08, and a
return code in R745CRTN. Processing continues for the next control
unit type.

System programmer response
Action depends on the reason for the
failure, which is indicated by the return code as follows: 04
GETMAIN failed for a caching subsystem during an attempt to obtain
storage for device counters. Increase the REGION parameter in the RMF procedure, and restart RMF.

08
An I/O error occurred in a caching subsystem during an attempt
to obtain device counters. If the failure is intermittent, it might
result from a RESERVE having been issued against a 3390 device. Use the device number to locate the failing control unit. If
the message is issued in consecutive intervals, and no RESERVE is
active, search the problem-reporting data bases for a fix. If there
is no fix, save the SMF74-5 records and the system log. Report the
problem to the IBM® Support Center.

20
The request to obtain device counters failed with an AOM return
code 4 and reason code 20. AOM could not access the RMF internal output buffer to store the device
counters. Search the problem reporting database for a fix. If there
is no fix, save the SMF74-5 records and the system log. Report the
problem to the IBM Support Center.
36
At least one storage director had no path available when RMF attempted to obtain device counters. Ensure
that there is a path to each storage director or each caching subsystem
from the system on which RMF is
running.

40
A caching subsystem had no path available to it when RMF attempted to obtain device counters. Ensure
that there is a path to each storage director or each caching subsystem
from the system on which RMF is
running.

56
RMF received a bad return
code from AOM when attempting to obtain device counters and the AOM
reason code returned is other than 04, 16, or 20. This error might
result from an online device with no operational path that RMF uses to retrieve the device counters.
Make sure that there is at least one operational path to the devices
of the cache subsystems from the system on which RMF is running. Search the problem reporting
database for a fix. If there is no fix, save the SMF74-5 records and
the system log. Report the problem to the IBM Support Center.

60
An I/O error occurred in a caching subsystem during an attempt
to obtain device counters. The attempt to obtain the device counters
was terminated by a timeout condition. Use the device number to
locate the failing control unit. Search the problem reporting database
for a fix. If there is no fix, save the SMF74-5 records and the system
log. Report the problem to the IBM Support
Center.
