Re: Restoring system using make_tape_recovery tape

Also, I have observed that everytime I got
os_arch_post_c
os_arch_post_l are missing while restoring the backup from make_tape_recovery backup.

is it absolutely safe to depend upon make_tape_recovery for system recovery or is there any other backup strategy/product more advisable over this one?

Re: Restoring system using make_tape_recovery tape

well you could use the mksf command to create the files for the tape. But before that please try this:

rmsf -H 0/5/1/0.5.0
ioscan -fnC tape
insf -C tape
ioscan -funC tape

This will remove the device files for the tape. Then we will rescan the io bus for any tape devices. Then you will recreate the device files. let me know if you see anything different.
"The difference between me and you? I will read the man page." and "Respect the hat." and "You could just do a search on ITRC, you don't need to start a thread on a topic that's been answered 100 times already." Oh, and "What. no points???"

Not sure why you aren't seeing the device files but if all you want to do is rewind the tape try:

mt -f /dev/rmt/c4t5d0BEST rew

Re: Restoring system using make_tape_recovery tape

Rewinding the tape isnt my problem but I want to know what could be the reason to
ERROR: Missing script "/opt/ignite/data/scripts/os_arch_post_c".
ERROR: Could not execute the script:
"/opt/ignite/data/scripts/os_arch_post_l"; not found or not
executable.

btw, Rewind works if i choose the diff driver as suggested by you

Re: Restoring system using make_tape_recovery tape

/opt/ignite/data/scripts/os_arch_post_l is a post load script.

/opt/ignite/data/scripts/os_arch_post_c is a post config script.

I really think that you are getting these errors because of a bad tape or a bad drive. Try a different drive.
