make_tape_recovery device failed

[Andrew Pollard]

Hi,
I have started trying to do a make_tape_recovery on a RP8400 using an LTO1. I am receiving the error "This is not a character special device" "Check tape device failed". A make_tape_recovery on a DDS tape would use /dev/rmt/0mn, would I still use /dev/rmt/0mn with LTO1 or just use /dev/rmt/0m or is this not causing my problem?

Thanks

Hi,
you need norewind tape device to use with IgniteUX because tape should be bootable.

Hi again.
Can you tell me LTO is connected with FC or SCSI?

[Andrew Pollard]

Hi,

The LTO is connected using scsi.

Maybe this:

insf -e

This will recreate the device drivers, just in case you've accidentally overwritten your tape device driver.

You should also look at the permissions on the device driver ll /dev/rmt/0m or whatever device your script uses.

Than you can boot from it.
Try then to recreate the device files with
insf -e
command

Hi Andrew,
Probably your /dev/rmt/0mn is not a character device file. You should get the following output with the file command.

# file /dev/rmt/0mn
/dev/rmt/0mn : character special (xx/y)

If not then it's a normal file. Delete it and recreate the special file by using "insf -e" command as told earlier.

Hope that helps.

Hi,

After reading all the suggestions and doing more investigation, it seems that "Too many hands in the cookie jar" has caused human error and not device file error.

I do believe that the problem is fixed. Thanks for all the suggestions and help on this problem. 10 points all around!!

Thanks

Andrew
