A while ago I posted to here saying that I could not get wbak to work to the 8mm tapes -- and that I didn't think it could be done, other people's comments notwithstanding. Well, people sent in comments on what worked for them. Many of them were _very_ complete in their descriptions and in their setups. (Thank you, everybody.) Well, I decided to poke around some more, and -- lo and behold! -- it works. --> wbak directory -dev m0 -f 1 [-nhi -pdtu -anyotheroptions] sends the output to an 8mm tape drive that is at SCSI ID 1 (/dev/rmts8). It takes a _long_ time before it satrts doing anything, and this may be what was throwing me off track. You _do_ need to have 10.3 going, but we don't have any patches loaded onto the node, so the base 10.3 installation should do the trick for everybody. The tape drive I have is just an Exabyte -- not from HP/Apollo, so there's nothing funky there either. It appears that you just have to be patient. I successfully put out 2 wbak files, indexed them (I didn't try a restore, because I was running out of time before the Omniback backups kicked in), and used 'rwmt -dev m0 -index' to look at the tape files as well. Everything works fine. Here's the status of the node where I worked from : >>> $ bldt -n //arwen >>> **** Node 29D5E.27D73 **** "//arwen" >>> Domain/OS kernel(7), revision 10.3, August 22, 1990 3:32:49 pm >>> >>> $ ts /usr/apollo/bin/wbak /com/rwmt >>> Ver Name Time Stamp File Name >>> -------------------------------------------------------------- >>> c 1 write_backup 1990/03/20 10:01:02 CST (Tue) /usr/apollo/bin/wbak >>> c 1 read_write_magta 1989/04/05 16:54:47 CST (Wed) /com/rwmt >>> >>> $ /systest/ssr_util/scsi_info >>> Target 0: >>> Target does not exist >>> >>> Target 1: >>> Device Type: Tape (Removable Media) >>> Vendor: EXABYTE >>> Product: EXB-8200 >>> Rev Level: 425A >>> ANSI version compliance: SCSI-1 >>> >>> Target 2: >>> Device Type: Tape (Removable Media) >>> Vendor: EXABYTE >>> Product: EXB-8200 >>> Rev Level: 425A >>> ANSI version compliance: SCSI-1 >>> >>> Target 3: >>> Target does not exist >>> >>> ... So I guess the solution is -- keep trying -- give the wbak time -- make sure you're at 10.3 -- make sure your tape drives are configured right (SCSI IDs 1 & 2) with the devices built right. -- jt -- John Thompson Honeywell, SSEC Plymouth, MN 55441 thompson@pan.ssec.honeywell.com Me?
