MD110 BC9 dumping problem

[Sync182]

G'Day from Oz!

I have a problem with a customer's BC9 MD110: the auto-dump (via DUFQI) keeps failing.

When I attempt to force a manual dump (using DUSYIUMP=ALL,PRINT=ALL the dump goes through to the CHECK READING OF RELOAD DIRECTORY stage, then stalls and the IPU resets, logging me off and dropping my connection (I have to dial back into the PABX - that's OK). REL2 is valid, REL1 is invalid.

I've restarted program units ALH1, BUP, CNH1, DRDH, DRDM & FIH in LIM1, and also units BUP & DRDR in LIM2 (2-LIM system).

I believe the system is running patch 44 at the moment - the customer HAS been told they should upgrade to patch 58 but have not responded...would the patch version make a difference?

Any tips, hints or suggestions?

I suggest you to try with a new pair of IPU & HDU, if you can find

Try to dismantle hard disk and reassemble with the controls and try to run the dump.
BLEQI, Fimoe, IOSIE, IOSII, Fimoe, BLEQE.

Thanks - figured it out using BLEQI, FIMOE, FIFTI, FIMOI, BLEQE on both SYSSUBFSs.

FIFTI reported errors on SYSSUBFS11 and fixed them, all appears OK to this point (customer hasn't reported any alarms since).

I'm happy....

I have had many systems with failing file systems on BC9, each time it has been due to the HDU getting old

On emergency situations when HDU not responding, you can try to plug out HDU and kick with a solid tool to the hard disk several times. It really works But only once!!!
