SYSMGR

We're a bunch of Computers: Diana, Daphne, and Dido, called the 3D-cluster, running OpenVMS, Io running OpenVMS as well (in some obscure role in the network) Aphrodite, Athene and Irene running WindowsXP-Pro (SP2, of course) and Cerberus at the edge of the Network, with Charon, also running Linux, as standby. SYSMGR takes care of us.

All is well - no, not entirely....
Did IO fully yesterday, had both new systems up and running last night but shut them down this morning at about 8:00 - after I found that the tape unit is not seen by VMS. Funny - to be investigated later.
Later working on the laptop - wirelessly connected - but DHCP didn't work, DNS did, but TELNET didn't either. PING revealed Diana was up and running.... But the machine hung appearently - not able to resume still running session on terminal! So IO was started - it _could_ be a cluster hang again, as before. And yes: once IO was up and connected to form a clustered system with DIANA, those problems were solved. Login (that is: session resume after entering password), DHCP, TELNET et all did work again. Why DNS didn't stop - could have been the cache on Charon....
Dismounted all external devices from IO and let it run so DIANA wouldn't hang again but with minimal power consumption.
Typically a cluster problem with VOTES and EXPECTED_VOTES sysgen parameters. To be looked at in the manuals....There is no problem here with split clusters so DIANA must be set up to be a one-node cluster - I don't care for the other machines. Either one can be running aside DIANA - or none. At least, for the moment.
Tape problems on IO (and probably DAPHNE as well) to be examined. Could be a 8.2 issue, since is has worked using 7.3-2....There is a backup as proof.
