SYSTARTUP_VMS.COM

Greetings,

I found this command line left behind by previous system admin in the SYSTARTUP_VMS.COM: "define/sys/exec PWRK$KNBDAEMON_DEVICE "EWB0:"

Does anyone know what he was doing with this device?

According to my LANCP configuration:

LANCP> sho dev ewb0/char

Device Characteristics EWB0:
Value Characteristic
----- --------------
1500 Device buffer size
Normal Controller mode
External Internal loopback mode
00-10-18-10-A4-B8 Hardware LAN address
Multicast address list
CSMA/CD Communication medium
FF-FF-FF-FF-FF-FF Current LAN address
128 Minimum receive buffers
256 Maximum receive buffers
Yes Full duplex enable
Yes Full duplex operational
TwistedPair Line media type
1000 Line speed (mbps)
Disabled/No Failset Logical LAN state
0 Failover priority

I don't have any issues with this device. I am new to VMS and I would like to get a better understanding my Alpha server better.

Thanks,
J

J,

Some earlier versions of Pathworks did not know
about all network devices and (I think) defaulted
to using the 1st (i.e the "A") device if multiple
devices existed.
By defining the logical that you have found, this
tells Pathworks to use that device (or list of
devices).

Please read the releasenotes for your pathworks version (SYS$HELP:PWRK* or ASO*). The use of this logical name is described in there.

Jorge,
From the release notes of Advanced Server V7.3A ECO 4:

Thus, for TCP/IP hosts with multiple network interfaces, you must define both the PWRK$KNBDAEMON_DEVICE and the PWRK$KNBDAEMON_IPADDR logical. If both logicals are not defined, the server will not start and an error message will be displayed, indicating that both must be defined.

Over here, we always define both logicals, even on systems with only one NIC.

OTOH, if you do not plan to use Advanced Server, you can remove the definition of this logical from SYSTARTUP_VMS.COM.

Regards,
Kris (aka Qkcl)

Chris - Yes, we're currently using the Advanced server edition.

Do you use the SYS$STARTUP:SYLOGICALS.COM file? Thats where I would have had this logical moved to if possible just to keep all logicals in there.

Since you found the reason for the logical I would suggest adding a comment near the logical so that if someone else investigates they already have the answer to the what the logical does.
