IBM PS/2 - Configuration problems with 5 or more adapters and SCSI
Applicable to: World-Wide
Symptom:
1. Configuration errors after configuration is setup.
2. System requires excessive time to configure or system hangs during configuration setup..
One or more of the following adapters may be involved :-
Token Ring
8514/A
3270
SCSI Adapter with CACH (1 or more)
SCSI Adapter without CACHE (1 or more)
S/370 Channel Emulation Adapter/A
Problem Isolation Aids:
Certain adapters require specific (unique) addresses in ROM (Read Only Memory). If configuration difficulties are experienced, the following steps should be taken :-
a. Remove enough adapters so that a maximum of 4 are left in the system (there is no installation order). Run setup. Power off the system.
b. Add another adapter and run setup. This step should be repeated as many times as necessary to complete this system's unique configuration.
c. If after adding all adapters, one at a time, setup has successfully resolved all conflicts, the user is done. If conflicts remain after steps A and B, then proceed to step D and consult 'Additional Information' which follows below.
d. Remove enough adapters so that a maximum of 4 again remain. Rearrange these 4 adapters into different slots. Run setup. Proceed to step B.
Additional Information:
1. Any remaining configuration conflicts can usually be cleared by making manual changes. This can be done by selecting "Set configuration" from the main menu, followed by selecting "Change Configuration". At this point you will see an asterisk (*) next to the adapter resource that is in conflict. You may alter the setup selections manually on some adapters until all conflicts are resolved, (this is done using the PF5 and PF6 keys, to step through the allowable configuration selections for a given adapter line item). After all conflicts are resolved using this method, PF10 should be pressed to save the configuration. Conflict resolution will be apparent because the asterisk should not be present on any adapter line item.
2. Token Ring and broadband/baseband adapters can coexist. If the system has one of each kind, they may both be configured to "primary" by the setup program.
Two token ring adapters can coexist. One will be configured as "Primary", the other as "Alternate" by the setup program. Two broadband/baseband adapters can coexist, setup will configure one as "Primary", the other as "Alternate". Altering or assigning a "Primary" adapter to "Alternate" may allow certain configurations to complete successfully, but the "Alternate" selection for a broadband/baseband adapter should be selected only if a "Primary" broadband/baseband adapter has already been configured.
Note:
Special application software considerations may apply to the "Setting-Up" of the adapters. The user should consult any literature that accompanied the application software to confirm these considerations.
Fix:
None.
