Upon completing an INSTALL and RELOAD, STAGEMAN does not see my BULDACCT-FIX staging area. I ran Patch/iX to set things up again, but it will not allow me to create the BULDACCT-FIX staging area because it says it already exists. STAGEMAN will not allow me to delete it because it doesn’t see it. I tried to purge the folder, but I get file security errors. How can I fix my staging area?

Goetz Neumann replies:
That is normal. Stage/iX relies on information found via the LIF directory, which got deleted by the ISL>INSTALL. There is a RECOVER command in STAGEMAN for that purpose.

Is there a way for us to get a hardware map using the STM? I don’t want to reboot just to get a hardware map, but I do not know another way to do this.

John Clogg replies:
The map that you get when you enter the MAP command is constructed by a hardware scan, not from the system configuration. The reason it displays so rapidly is because the map is built when the STM daemons are first launched. To re-scan the system and refresh the map, use the REMAPSYSTEM command (can be abbreviated ‘RS’).

CSTM will tell you how long it’s expected to take and request confirmation. Once you confirm, the re-mapping function begins. After it completes, the map command will display the new map. If you want to know when the re-mapping operation is complete, you can type WAIT at the prompt and CSTM will suspend until the map completes. You get another prompt when it is complete.

What things count against a system’s user license?

Gavin Scott replies:
This has been well documented and vetted in the HP 3000 FAQ: www.3kassociates.com/faq/hpfaq03.html#3.10.

Are the SuperDLT Tape drives supported on HP 3000 N-Class boxes?

Giles Schipper replies:
According to the 2003 MPE I/O roadmap presented by Jim Hawkins, “SDLT with SDLT data cartridges stores 110GB uncompressed and achieves 11Mb/sec sustained IO rate. It is able to READ DLT IV cartridges written by DLT4/7/8000 devices. During our initial evaluation of SDLT devices we found some minor incompatibilities with our existing tape drivers. These incompatibilities along with uncertainty (at that time) about HP’s Tape Roadmap and the fact that they are not 100 percent media compatible with existing DLTs led us to the decision to not invest in these devices.” The bottom line: SuperDLT is not supported by HP. Whether or not they will work with the N-Class is unclear to me.
