First task in the reconfiguration effort is to reassign drive letters to the SIMH VAX 3900 simulator drive mappings.<\/p>\n

According to best practice drives should be mounted in the SYLOGICALS.COM configuration file.<\/p>\n

The hardware-based BUBBLE configuration is as follows:<\/p>\n

$ msc   == \"MOUNT\/SYSTEM\/CLUSTER\"\r\n$!MSC   DSA0:           \/SHADOW=($255$DKA0:,$255$DKA500:) BUBBLESYSTEM SYSTEM$\r\n$ MSC   DSA1:           \/SHADOW=($255$DKA100:) BUBBLEDATA01 DATA01$\r\n$ MSC   DSA2:           \/SHADOW=($255$DKA200:) BUBBLEDATA02 DATA02$\r\n$!\r\n$ MSC   $255$DKA300     BUBBLEBACKUP    BACKUPS$\r\n$ MSC   $255$DKA400:    BUBBLEKITS      KITS$\r\n$ MSC   $255$DKA500:    BUBBLEPAGING    PAGING$\r\n<\/pre>\n
Note that DSA0: is commented out – this is documentation. The shadowing of the system disk is configured in the MODPARAMS.DAT configuration file and is applied to the system disk directly so no drive remapping is required.<\/p>\n
So these need changing to use the DUA drive designations now in-force using the simulator:<\/p>\n
$ msc   == \"MOUNT\/SYSTEM\/CLUSTER\"\r\n! SIMH specific configuration\r\n$!MSC   DSA0:           \/SHADOW=($255$DUA0:) BUBBLESYSTEM SYSTEM$\r\n$ MSC   DSA1:           \/SHADOW=($255$DUA1:) BUBBLEDATA01 DATA01$\r\n$ MSC   DSA2:           \/SHADOW=($255$DUA2:) BUBBLEDATA02 DATA02$\r\n$!\r\n$!

One of the good habits that Steve Davidson persuaded me to adopt was to add a changelog to each of the configuration files. Here is the SYLOGICALS.COM changelog with an updated entry:<\/p>\n

Following a reboot the drive mappings all look a lot nicer!<\/p>\n

Next is licenses. Typically where networking isn’t available this is done by registering the VAX-VMS license and either a DECNET license or TCPIP license, then copying the whole license file across the network.<\/p>\n
The next thing to sort out (and this is where is starts getting a bit tricky for me!) is networking. I’ve contacted PROCESS who supply the MULTINET VMS networking package that BUBBLE uses. However, I thought that the networking device available to the SIMH simulator in the VAX 3900 configuration would be different to the one in the VAXstation 4000\/90. The startup log file for decnet confirms this:<\/p>\n

What I might do now is take a backup of the system disk and the re-run the network configuration script. The potential problem with this is that the script resets cluster passwords – I learnt this the hard way and it’s now a well documented issue<\/a>.<\/p>\n
So I decided to pick a standard password, do as recommended and take a copy of the generated configuration file, hand edit all the passwords and then run that version. After a reboot we see DECnet coming up successfully!<\/p>\n
