Friday Fine-Tune: Moving all disks at once
March 17, 2017
I want to take all my disks, system volume set, and the user volumes, and move them to another machine that has no disks. How can I best do this?

You might use SYSGEN to create two different config groups in the SYS account, one for the old system (e.g. CONFOLD), and one for the new system (e.g. CONFNEW). To create the new config you might start with one of the existing config templates, e.g. CONF9x8.SYS for 3000/9x8 systems. Use
BASEGROUP to open it, adjust IO to your needs and
KEEP it as CONFNEW.
Just make sure that every disk gets an LDEV in the new config. Paths and LDEVs (except for LDEV 1) do not need to be the same on the new system. MPE/iX will notice (and "collect") all available volumes during bootup (as long as they are "visible" by a configured LDEV number).
Shutdown the system, plug disks into the new box, power it on, boot from the primary path (or enter the appropriate path for LDEV 1) and at the ISL prompt do a
START NORECOVERY [NOSYSSTART] GROUP=CONFNEW.
You might also need to adjust NMCONFIG with NMMGR as a different system will probably have the LAN cards at a different physical path. In case you make a copy of NMCONFIG, make sure it stays on LDEV 1 (
We replaced LDEV1 on our HP 3000, did an INSTALL. Then we did
The MPE-filespace was restored normally, but the HFS filespace was not. RESTORE told me to use CREATE=PATH which I then did. The DIRECTORY is on my STORE tape - so what went wrong?
Wolfgang Kinscher, and Gilles Schipper reply:
If you are planning an install keep this in mind: Do not specify the option "DIRECTORY" with a partial (DATE>=) backup. STORE will not put the HFS directory structure on tape. Do the following instead: STORE ;*T;DIRECTORY stores all of your MPE/HFS directories on tape. Then do your partial backup without DIRECTORY option
After the install, first restore your DIRECTORY with RESTORE *T;;DIRECTORY and then restore your partial and your latest full backup respectively.
