diskdump fails on x3850 (x86_64)

[Ciju Rajan K]

Hello folks,

Diskdump on x3850 with adp94xx driver is not working (Redhat Enterprise Linux 4.6). 
'Service diskdump restart' fails. Is there any plan to support it?

Thanks
Ciju

We looked at the code and there seem to be atleast two functions that 
may be required in the driver to support diskdump, dump_poll and 
dump_sanity_check as part of Scsi_Host_Template structure.  Different 
drivers have their own way of implementing these routines in the driver 
code. Hence we wanted to ask if the current developers of adp94xx can 
provide implementation for these routines.  The driver version that we 
have seems to be adp94xx - '1.0.8-13'

Regards,
Chandru

Erm, you'll need to take this up with Red Hat and Adaptec support.  The
adp94xx isn't the in-kernel driver, it's one those companies have
supplied to RHEL4.  If you can reproduce the problem with the in-kernel
aic94xx driver then sure, we could take a look at it.
