Crash analysis

Post by zeiszler » Tue Jul 26, 2022 6:13 pm

With a crash dump from an X86 is there a way to analyze the dump on an Itanium system?

Unable to determine platform; no platform bits are set in dump
%SDA-E-NOTI64DUMP, dump file does not contain an OpenVMS I64 dump

You would need a running system with the same architecture as the crashed one for crash analysis. The cross tools do not seem to include a SDA version for x86-64.

Can't you boot from the installation media (.ISO) ? Or try a minimum boot. ANALYZE/CRASH should work.

Did the crash system at least boot once after the crash ? Is so, you should have a CLUE file (CLUE$node_ddmmyy_hhmm.LIS) in SYS$COMMON:[SYSERR]. This would be a good start to look for a crash problem.

As you seem to be running some version of VSI OpenVMS x86-64, you should also have access to VSI support.

re: The cross tools do not seem to include a SDA version for x86-64.

The cross-tools kit does in fact contain a cross-version of SDA...and here's an example of how you'd use it:

Code: Select all

fred_system> @X86_XTOOLS$ROOT:[EVAX.XSDA]X86_SDA.COM STAGED$:[DUMPS]BARNEY_OPERCRASH_220727_1746.DMP
%X86_SDA-I-Defining SDA$READ_DIR...

...analyzing an x86-64 compressed selective memory dump...

Dump taken on 27-JUL-2022 17:46:02.88 using version V9.2
OPERCRASH, Operator forced system crash

SDA>
VSI recommends that the native version of SDA be used, but in a pinch the cross-built/cross-architecture version will do the job.

Hi,

I'm interested in the CLUE file from this OpenVMS x86-64 crash, as I'm currently trying to bring back the CANASTA tool (VMS automated crashdump analysis tool from the Digital days) back to VSI.

I've sent you a PM.

Thanks,

Volker.
