Remote Backups to a Tape
My tape library is broken but backups still need to go on .I have 2 boxes running Solaris 10
Got SCSI tape drive attached to the DEV box ( my PROD Box has only fibre)
I want to take the prod backup from the DEV box using ufsdump. ie
/usr/sbin/ufsdump 0uvf DEV:/dev/rmt/1n /dev/rdsk/c5t600015D000032100000000000000482Ed0s0
I've entered the PROD server name in the /.rhosts in DEV and vice versa
tape status via PROD is not possible
root@PROD # mt -f DEV:/dev/rmt/0 status
DEV:/dev/rmt/0: No such file or directory
in DEV it works
root@DEV # mt -f /dev/rmt/0 status
HP Ultrium LTO 2 tape drive:
sense key(0x0)= No Additional Sense residual= 0 retries= 0
file no= 0 block no= 0
root@DEV #
The two servers are on the same network and can ping each other. There are also some NFS mounts between the two
Is there a step I'm missing out ? which other files should i configure
Thanking you
Msoro

drives). See for further details.
