X86 Release Notes

2. New LFC OE199001 and

updates to Repair Code 90

(continued)

Occasionally, recursive controller inoperability problems

propagated to the bottom controller during FRUTIL

operations in HP StorageWorks Continuous Access.

Follow these steps to troubleshoot the above Recursive

Bugcheck error scenarios:

1. On “the other” controller, SET NOFAILOVER.

2. Issue a SET MULTIBUS_FAILOVER COPY=THIS

from “the other” controller that did not fail.

Note that there is a unit that is inoperative. Take corrective

steps to resolve that unit.

3. Host inoperability and

time-consuming events

Delays have been implemented into ACS during

time-consuming events to prevent host inoperability

issues.

4. Host aborts and OpenVMS

load

ACS improvements have been made to reduce the

number of aborts occurring under conditions of heavy

I/O loads.

5. Handling of SMART errors on a

device while RUN CONFIG

operations is executing

Issues surrounding SMART errors while the RUN CONFIG

command is running have been resolved.

6. SMART error eject flag ACS has been fixed to ensure that the SMART error eject

flag is treated symmetrical across both controllers after

FRUTIL operations.

7. Management enable flag ACS has been fixed to ensure that the management

enable flag is treated symmetrical across both controllers

after FRUTIL operations.

8. Bad disk drives moving from a

failedset to a spareset

An issue involving a defective disk drive being

inadvertently moved from the failedset to the spareset has

been resolved.

9. Clone utility and controller

memory leaks

The issue involving controller memory resource leaks

while the CLONE utility is executing has been resolved.

10. Controller inoperability during

controller replacement

(LFC 011C010)

The issue involving controller inoperability on the

surviving controller during the installation of a new

controller while using FRUTIL and resulting in Last Failure

Code (LFC) 011C010 (LED Code 25) is fixed.

11. Disk drive error handling

improvement

ACS has been fixed to substantially reduce issues

surrounding controller inoperability problems resulting

from the installation of bad disk drives into a subsystem.
