diskdump

[loco_vikide]

Hello,

Has anyone succeeded on configuring a dedicated disk device (/dev/cciss/c0d2) as a diskdump device on HP DL380 / HP DL585 running RedHat Linux RHEL4.0.2 (or lower). I keep getting the same error message even though I successfully formatted the disk with commands: "service diskdump initialformat" and "diskdumpfmt".

Then, I executed the command "service diskdump start" and got the errors:
Starting diskdump: [FAILED]
diskdump: diskdumpctl: /dev/cciss/c0d2 is not supported!

Please help. Thanks in advance.

Best regards,
Chris

Chris,

From reviewing the support docs on diskdump, it looks like the cciss driver support has only been added for RHEL 3U6.

I find no stated support from diskdump for the cciss driver on RHEL 4.

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=128788

My recommendation is submit a bugzilla report for cciss support on RHEL 4.

It does look like the cciss support is added to the 1.1.7 version of the diskdump utilities. What version of the utilities are you running?

Hi Craig,

You are correctt. CCISS driver is not yet supported for diskdump in RHEL4.

Thanks for your reply.

Happy Holidays,
Chris

Hi,

I am currently trying to setup diskdump on HP DL385's AMD's, with RedHat EL AS 4 Update 4 and get the exact same problem described by Chris above. The release notes from RedHat say its supported but I just cant get it to work.

Has anyone else seen the same problem?

Diskdump and kernel versions are:

# rpm -aq | grep diskd
diskdumputils-1.2.8-2
# uname -r
2.6.9-34.0.2.ELsmp

Please ignore my post. We are using RHEL AS4 Upd3, its time to upgrade! :-)

HP Smart Array Controller is not yet supported for diskdump running RHEL 4.0.2. It works with RHEL4.0.4 and later updates.
