Availability Manager v2.4 Data Collector on VAX

Art Wiens — Thu, 16 Dec 2004 11:37:38 GMT

Testing what AM can do for our environment. I installed Data Collector on one Alpha, and the Analyzer on my Win2K pc. Alpha is discovered and I can look at various things. Good stuff...(I have questions about event notifications as well, but not right now). I then tried to install the collector (HP-VMS-AVAIL_MAN_COL-V0204--1.PCSI-DCX_VAXEXE;1) on a test VAX and get this when starting:

$ @AMDS$STARTUP.COM start

%AMDS-I-EXLOGFILE, Executing AMDS$AM_AMDS_SYSTEM:AMDS$LOGICALS.COM

Copyright © 2003 HP Computer Corporation. All rights reserved.
%AMDS-I-RMSTART, starting Data Provider processing for this node
%AMDS-I-LOADSECDB, loading security database

This procedure has given up trying to start/stop a port
to the datalink. Please ensure your datalink device is
in working order.
%AMDS-S-RMSUCCESS, Data Provider startup successful

Went into AMDS$LOGICALS.COM and "hardcoded" (as suggested in the command procedure):

$ AMDS$DEF AMDS$DEVICE "EZA0"

AM then "seems" to start (no error messages) but the node doesn't show up in AM Analyzer.

I believe there was an older version of DECamds on this system previously and is possibly interfering with this new AM install.

Any suggestions?

Thanks in advance,
Ar

Art,

you can check, whether RMDRIVER is sending/receiving any packets via the LAN:

UCB UCB Addr Fmt Value Client State
--- -------- --- ----- ------ -----------
ESA0 81C51B00
...
ESA2 81F44E80 802E 08-00-2B-80-48 0017 Strtn,Len,Uniq,Strtd
...

SDA> SHOW LAN/DEV=ESA2/COUNT

(08-00-2B-80-48 is the Protocol ID for AMDS).

Does AMDS$GROUP_NAME match between the VAX and the GUI on the PC ?

Volker:

The device is created:

EZA13 87DA0A00 802E 08-00-2B-80-48 0017 Strtn,Len,Uniq,Strtd

And you may be on to something with the counts:

SDA> show lan/count/device=eza13

-- EZA13 80-48 Counters Information 16-DEC-2004 13:37:27 --

Last receive None Last transmit 16-DEC 13:37:08
Octets received 0 Octets sent 61752
PDUs received 0 PDUs sent 332
Mcast octets received 0 Mcast octets sent 61752
Mcast PDUs received 0 Mcast PDUs sent 332
Unavail user buffer 0 Last start attempt None
Last start done 16-DEC 10:49:08 Last start failed None

That may be a mess to look at...basically shows nothing received, but multicasts are being sent.

I didn't change any passwords or group names...the Alpha was discovered right after I brought it up, the VAX not.

Art,

What version of VMS is on the Alpha?
I had a problem where I was unable to see info
from a VAX and I believe it may be a version
difference between the collector and the data
provider on the VAX. I had the "latest" versions
running when I had the problem and never got it
to work and have not bothered trying to get it
working.

Regards
Dave

Art,

are the VAX, Alpha and PC on the same LAN segment ? When looking at our VAX AMDS LAN counters, it looks like it's sending one AMDS multicast msg every 30 seconds. It's also receiving 2 MC messages about every 30 seconds, as we have 2 other VMS systems running RMDRIVER on the same LAN.

Once you would be running the AM GUI (and the system gets discovered), the system would also send/receive non-multicast AMDS messages.

Volker.

David:

The Alpha 800 is VMS v7.3-2 (also testing our apps on that as well)
The VAXstation is VMS v6.2
The PC is Win2K SP4

Volker:

Of course! The test VAX is in our datacenter, my pc and the test Alpha are outside of the datacenter. Not sure why I didn't give you 10 points for that...reply and I'll give you one more ;-)

I'll see what the Network boys can do for me.

Thanks,
Art
