make_tape_recovery error

Can anyone shed some light on a possible remedy?

Given your similar problems, before doing anything else make sure that you can actually write to this tape drive. Trying dd'ing a file to this drive using a 2k blocksize and then read the file back. Use the tape drive to create a tar or cpio image. Only when you can do that should you try make_tape_recovery.

Your problems could be legion: Poor/incorrect termination, no termination power, SCSI bus length standards exceeded, bad tape dive, bad or write-protected media, bad controller, ...

Rather than entering a host of separate threads, you will find that keeping all this in one thread makes it easier to solve a problem as it then becomes possible to easily see what has gone before.

Hi Chad,

Your logs indicate I/O errors.
few things you could check:
1) ioscan -funC tape
2) mt -f /dev/rmt/0mn status
(replace /dev/rmt/omn with the correct one.
3) Is this write protected
4) Check /var/opt/ignite/recovery/latest/recovery.log
5) the script i use
#!/usr/bin/ksh

#

# 10-26-06: ~bahmed/scr/ignite-info.ksh

# make ignite tape for disaster recovery and store off-site

# igntie Version C.6.8.152
