A few weeks ago, a customer asked how to turn off an HP 3000 once and for all. While this is a sad time for the IT expert who's built a career on MPE knowledge, doing a shutdown by the numbers is in keeping with the rest of the professional skill-set you can expect from a 3000 manager.
Chris Bartram, who has launched and stocks a Technical Wikipedia (TWiki) for the 3000, offered all the details of turning off an HP 3000. "I have just performed last rites for a 9x8 server at a customer site," he replied, "and have been through the exercise a couple times before."
His steps did not include SOX requirements, but "might be useful," he said in his usual modest introduction. There are 10 steps Bartram details before switching off the 3000's power button.
Bartram reported that he first purged all accounts except sys, hpspool, and 3000devs (and had to log off all jobs, shut down the network, and disable system UDCs to do that). Then:
2) Reset/blanked all system passwords (groups, users, accounts)
3) Purged all groups from SYS account that I could (aside from in-use groups) as well as all users except MANAGER.SYS,OPERATOR.SYS, MANAGER.HPSPOOL.
4) Went through PUB.SYS listf (file by file) looking for anything that might be a job stream or contain user data (or anything not critical to keeping the system up) and PURGEd it
5) Went into VOLUTIL and condensed my discs
6) Created a group called JUNK.SYS (you would need to do this on each volset; this box only had the system vol set)
7) Wrote and ran a short script that copied NL.PUB.SYS (the largest file remaining on the system) into JUNK.SYS in a loop using filenames A####### and X####### until all disc space was used up
8) Typed the command PURGEGROUP JUNK.SYS
9) Went into NMMGR and changed IP addresses on the box to something bland/different; including the default gateway (also deleted any entries in the NS directory if there are any)
10) Sequentially PURGE @.GROUP.ACCT for all groups (leaving PUB.SYS until last)
11) Shut down the box.
I am reminded of the line from Citizen Kane, which I enjoyed on Turner Classic Movies this week. "Then, as it must for every man, death came to Charles Foster Kane." Nothing escapes death, but a proper burial seems in order for such a legendary system.
