Chapter 9. Troubleshooting Guide
Very Slow Response Times
Response times are in the multiple-second range. This is likely to be device definitions
in the SCON that do not have corresponding definitions on the host. Another possible
reason for slow response times can be having File Transfer enabled in the Device
Profile being used by fixed function terminals (although delays would only be in the
subsecond range). Only devices that need File Transfer should have it enabled (these
would StorageTek LMUs and PCs that need to exchange files with the host.
B5D Error Occurs at IML Time After Configuration
More than 32 Telnet client, LPD, or Socket sessions were configured on the SCON
without a Feature Activation Disk to support them. You will need to reconfigure to
reduce the sessions back to two or less, or add the Incoming Telnet Feature Activation
Disk to cover what is configured.
B63 Error Occurs at IML Time After Configuration
More TN3270E sessions were configured on the SCON than what the installed Feature
Activation Disks support. You will need to reconfigure to reduce the sessions, or add
Feature Activation Disk(s) to cover what is configured.
B71 Error Occurs at IML Time After Configuration
More CUs (and more Host Circuits) were configured than what the installed Feature
Activation Disks support. You will need to reconfigure to reduce the number of CUs
defined, or add Feature Activation Disk(s) to cover what is configured.
B71 Error Occurs After Microcode Upgrade
It is possible that the unit that you have upgraded microcode on was shipped at a level
that supported more LPARs in the base unit. At code levels prior to IL 3308, LINCS
software supported configurations up to 16 LPARs without requiring a Feature
Activation Disk to increase support for the number of LPARs. At IL 3308, the number
of LPARs supported without a FAD decrease to 4. At IL 3321 this number was further
reduced to 1 on the 1174-25S.
9F7 Error When Attempting To Load A New Configuration
A 9F7 error indicates unsupported features have been configured or a configuration
from another model has been copied onto the failing unit. (SCON-25L configuration
copied onto a SCON-22L for example.)
