Backup for 3B2 Node

1. Running back-up:

toau> bk (will backup toau, tobu, tocu) 
tjau> bk (will backup tjau, tjbu, tjcu) 

2. To check the backup, login to the A processor and check the backup.log, making sure the date is current.

toau_root > cd /tmp   
toau_root > ls -l backup.log 
-rw-rw-rw-   1 root     other       4386 Apr  9 03:59 backup.log 
toau_root > grep -i complete backup.log 
tobu: Backup Completed 
toau: Backup Completed 
Backup for all processors completed 

3. If a back-up fails because of a failed drive, redirect the back-up to a different processor's drive.
• a script /mail/bin/backup_tocu is already written to back-up tocu to tobu drive:

tocu_root > cat /mail/bin/backup_tocu 
ttape -o -t/dev/rmt/etape2 /dev/dsk/mir009 /dev/dsk/mir010 /dev/dsk/mir011 & 

-o (output) 
-t (tape device) 
/dev/rmt/etape2 - is directed in this case to tobu processor. 
/dev/dsk/mir009 is /to45000 (from the mount command) 
/dev/dsk/mir010 is /to50000 (from the mount command) 
/dev/dsk/mir011 is /to55000 (from the mount command) 
 
3b2 Drive Mappings: 
/dev/rmt/etape1 - au processor 
/dev/rmt/etape2 - bu processor 
/dev/rmt/etape3 - cu processor
