Tips to Reinstall Posix, DLT/LTO Tape Drives

What is the patch that installs Posix? I seem to have a corrupt version of Posix.

Donna Garverick of Allegro replies:

These are your instructions for MPE/iX 5.5 and 6.0.

Load the 5.5 or 6.0 FOS tape on a tape drive. For this example, tape drive on ldev# 7 is used. Log on as MANAGER.SYS

:FILE T;DEV=7
:RESTORE *T;@.HP36431.SUPPORT,I0036431.USL.SYS;CREATE;SHOW
:STREAM I0036431.USL.SYS

Please note:

  • HP36431 is the master product number of the Posix 2 Shell.
  • I0036431.USL.SYS is the installation file.
  • When launched, the job I0036431 should run for less than 5 minutes. When it is done, the Posix environment is re-installed.

[Gilles Schipper notes the process for 7.5 is the same, working from the MPE/iX 7.5 FOS tape.]

I have access to a Tandberg Data Ultrium LTO 3 tape drive. It has a SCSI Ultra160 interface. Would I have any luck hooking one up to an N-Class?

Chad Lester of MPE Support Group replies:

It's worth trying. You might have issues with the dual-port SCSI cards. Also, make sure the firmware is the latest on the single SCSI U160 card.

We recently upgraded our customers to the hot-swappable LTO drives designed for the TA-5300 Array. The array is $350 with an SCSI Cable. Two Q1540A LTO 3s are $1,350, for a grand total of $1,700. That includes phone support from us for installation. 

I have a DLT4000 that will connect to an HP 3000 on path 32.2.0. How do I set the 12 dip switches on the back of the DLT for this path?

Mark Ranft of Pro3K replies:

Off of Google, I’ve found this:

For HP 7980S emulation, 

     1,2 - OFF

     3,4,5 - ON

     6,7,8,9 - OFF

     10,11,12 - SCSI ID (suggest all OFF)

So 10 is the 4's place
And 11 is the 2's place
And 12 is the 1's place

If 10, 11 and 12 are off (down), the SCSI ID will be zero.

Gilles Schipper of GSA adds:

I believe there are two different versions of DLT4000. One has a single-ended SCSI interface and the other has a FW-SCSI interface. I think the one Mark described is for the former.
