The errno 9 means:EBADF bad file number

Check the log file "/var/opt/ignite/logs/ makrec.log1". It should tell you why it failed

Maurice:

You might be interested in document #KBRC00001438 (/usr/bin/dd failing during make_recovery) upon which I stumbled when searching for something else...In part:

PROBLEM: When running make_recovery, it will start and after a while fail with the following error:

make_recovery(472): /usr/bin/dd failed,res=512,errno=0

RESOLUTION: This error usually indicates a scsi error accessing the tape. This can be
caused by bad tapes, a bad drive, a dirty drive or even corrupted device files.

The first thing to try is running a cleaning tape through the drive two or three times. This is the easiest and quickest of the possible resolutions.

Next, try a different tape, preferably new, if one is available.

If the problem still persists, check the system for the latest scsi patches.
