If I do the following:

:SYSGEN CONFIG,TESTCFG
SYSGEN> IO
IO>HO
IO>EXIT
SYSGEN>KEEP
SYSGEN>TAPE

Which group am I creating the SLT from, CONFIG or TESTCFG?

Jon Ose replies:
TESTCFG. Remember, docs.hp.com is your friend:
“The command for the SYSGEN utility is SYSGEN. SYSGEN has four positional parameters:
SYSGEN [basegroup] [,newgroup ] [,inputfile] [,outputfile]

“The basegroup parameter specifies the group in the SYS account that contains the configuration data file set to be used or changed. The newgroup parameter specifies the group used to store data. If you do not specify newgroup, SYSGEN stores any configuration changes in the base group by default. If the group specified by newgroup already exists, SYSGEN asks, at keep time, whether or not it should overwrite that group with new information. At keep time, if the user does a KEEP with no parameters, SYSGEN keeps the current base group unless newgroup was specified, in which case the group given is used.”

Since I’m replacing my old Model 10 with a Model 20 on MPEXL_SYSTEM_VOLUME_SET, this will of course require a Re + INSTALL. What’s the best way to re-instate my network config files? Just restore NMCONFIG and NPCONFIG? Can I use my old CSLT to re-add all my old non-Nike drives and mod the product IDs in Sysgen, or do I have to add them manually after using the Factory SLT?

Gilles Schipper replies:
Do the following steps:
- using your CSLT to install onto LDEV 1
- modify your i/o to reflect new/changed config.
- reboot
- use volutil to add non-LDEV1 volumes appropriately
- restore directory or directories from backup
- preform system reload from full backup - using the keep, create, olddate, partdb,show=offline options in the restore command
- reboot again
No need for separate restores of specific files.

We had another hard drive fail this weekend. It was in an enclosure of old 2GB drives that we really did not need, so I just unplugged them and rebuilt my volumes without them. However, when I boot up I get error messages that path 10/4/0.20-26 can’t be mounted. How do I get rid of these messages?

Gilles Schipper replies:
You can safely ignore the messages, but if you want them not to reappear, simply remove those devices from your IO configuration via SYSGEN, keep the new configuration to config.sys and reboot with a start norecovery. When you’re back up again, you should create a new slt tape.

Paul Edwards adds:
Use SYSGEN with DOIONOW or IOCONFIG to delete them. No reboot is required.

I am trying to put together a 4/40 tape library. It came with one tape drive. When I add the second it says I need to update the firmware. There are two passwords on a 4/40, one is the administrator password, the other is the “service” password. I can’t seem to get the “service” password. I would think that I need that password to update the firmware. Has anyone ever reset the service password on a Surestore 4/40?

Bob J replies:
You do not need a password to update the firmware. That admin password can be changed, but most folks just leave it at 1234.

When running programs in a job stream, is there some way to prevent the page eject that is generated each time a RUN <prog> is used? Seems to me that I read something about this long ago, but I cannot find anything on it now.

Michael Anderson replies:
Substitute “XEQ” for “RUN”.
