System hang

olive_wide — Sun, 19 Jun 2005 00:22:14 GMT

ES45,Raedon 7500 Display Card.
When I boot with Openvms7.3-2 Install CD to make system-disk backup:
P>>>boot dqa0 -flags 0,0
Starting...
But when running the following:

Please choose one of the following:
1)Upgrade,intall or reconfig Openvms alpha version v7.3-2
2)Display products and patches that this procedure can install
3)
...
7)Execute DCL commands and procedures
8)Shut down this system
Enter CHOICE or? for help:(1/2/3/4/5/6/7/8/?)_

Here,we will input the number,but the system hung,can only power off or reset to restart the server.Sometimes,it is good,but somethimes,the system hung while it is waiting for input something.
What's the reason?Is it the display card?I know this raedon 7500 card is not well supporting the alpha Server.

Hi,
what kind of hung?
I guess you are using graphical console; can you use serial VT terminal instead?

I have seen similar hangs (boot VMS with a graphics card, but don't run it with Motif) on older systems at customer sites, but nobody cared for a solution. Sometimes it worked when I immediately responded to the input request. Does it go better when you use the serial port?

P>>>boot dqa0 -flags 0,0

The binary CD-ROM should have all valid roots from 0 to FF, so you don't need to specify the flags argument unless the console setting is strange.

I want to get the solution because I met the same problem in the following instance:
I made a program XX.com and run it in systartup_vms.com,the program like this:
You can make choice:
1.system startup with tcpip startup
2.system startup without tcpip startup
3....
You choice is 1/2/3)_
When I run this program in systartup_vms, sometimes,the system start well, but sometimes the system hang while waiting for the input. I think it is the same reason with the binary CD startup hang.
I didn't try the serial port.It is useless even the serial port connect is good.

Olive,

Just _HOW_ do you specify that choice?

The only valid options I am aware of are
1A. Boot into sysboot ( >>> B -fl = ,1
SYSBOOT> SET USER1 (or 2, 3, or 4)
SYSBOOT> C
and then in SYSTARTUP_VMS:
$ CHOICE = f$getsyi("USERn")
and act upon CHOICE

1B.
SYSBOOT> SET STARTUP

or

2. in SYSTARTUP_VMS:
$ OPEN/READ inp OPAo:
$ READ inp CHOICE /timeout=...

Be REAL carefull in fiddling with STARTUP (option 1B). I would not advise it, but had to add it for completeness.

By far the easiest option is 2 (READ from OPA0:).

If you want to boot from CD, into the standalone menu, then
>>> SET CONSOLE SERIAL
will help, but remember to reset it to GRAPHICAL before booting into your graphical console again.
Another solution is to just attach a serial console, and leave the setting to SERIAL.

hth,

Proost.

Have one on me.

jpe,
In fact,I use the following as you suggest:
$ OPEN/READ inp OPAo:
$ READ inp CHOICE /timeout=...
I can extract a part of my program:
$OPEN /READ/WRITE CHN_OPA0 OPA0:
$READ CHN_OPA0 ANS$TEMP /PROMPT="YOUR CHOICE[1/2/3/4 DEFAULT 4]: "
$ANS$TEMP = F$EDIT(ANS$TEMP, "TRIM,UNCOMMENT,UPCASE")
$IF ANS$TEMP .EQS. "" THEN ANS$TEMP = "4"
$IF ANS$TEMP .EQS. "1" THEN GOSUB ..
$IF ANS$TEMP .EQS. "2" THEN GOSUB ..
$IF ANS$TEMP .EQS. "3" THEN GOSUB ..
$IF ANS$TEMP .EQS. "4" THEN EXIT
It is this program that cause the system hang.
Do you know others ways to avoid the hang?

Re: System hang

Jan van den Ende — Mon, 20 Jun 2005 02:01:40 GMT

Olive,

I would give this piece of cade an "emergency exit"
Add a /TIME_OUT=n/ERROR=label
n is the number of seconds to wait for an actual reply (max 255)
"label" = the label to proceed to on timeout.
In "label:" you can write a specific text to sys$output to identify your code stream, and then exit.

Let's find out what happens.

Proost.

Jan van den Ende — Mon, 20 Jun 2005 02:12:54 GMT

Oops.

I only re-read the whole thread after answering :-(

My guess now is that you have an issue with your console (or its connection), because you can not answer to the cd boot menu neither.
I DO hope you have some way to still make the above change, which I now guess will always take the timeout.

Do you have any possibility to connect a serial console (a VT, or a Terminal Emulator)?

Proost.

I have the same behaviour when I boot minimal on e.g. an AS500 and have worked for a few minutes. Never found why ...

Wim

Re: System hang

Antoniov. — Mon, 20 Jun 2005 03:15:31 GMT

Olive,
in your example you open twice OPA0:, first time with
$ OPEN/READ inp OPAo:
second time with
$OPEN /READ/WRITE CHN_OPA0 OPA0:
I hope you close inp device before open CHN_OPAO

What hardware? In particular: what processor type (pre-EV56, EV56, EV6?)
I had similar problems on a EV56-based system and 3DLabs Oxygen VX1 in graphics mode (hung DECW$SERVER process looping heavily), it turned out the driver was EV6-optimized and wouldn't work on EV56.
Since Radeon is even 'newer', it could well be that the driver of thsi card is optimezed for EV6 as well and won't run properly on EV56 or earlier.
It didn't matter whether I had consoe set th Graphics or Serial, the only way to get around it was disableing DECWindows, or install a different card.

Wim Van den Wyngaert — Mon, 20 Jun 2005 04:50:55 GMT

Willem : he asking in DCL if TCP should be started. So, decw isn't started yet.

Just tried to boot minimal with my AS500. After 5 minutes the machine was blocked.
I power cycled it and tried again. No blocking.
I booted normal and then minimal again. No blocking.

I noted that job_control was doing a few IO's while I was waiting and doing show sys.

Nothing special in oplog.

Volker Halle — Mon, 20 Jun 2005 05:31:06 GMT

Olive,

as you seem to be able to easily reproduce this, did you ever try to force a crash, if the system is hung like that ?

CTRL-P would not work on the graphics console, so you need to find and press the HALT button. Do you get the console prompt (>>>) ? Can you then enter CRASH and hit to force a crash ?

I would not expect any obvious problem to be seen in such a forced crash, but even testing this, may show, whether the problem is between the graphics hardware and the console firmware and/or OpenVMS.

Trying to get a valid crashdump when booted from the CD would require some setup work (DOSD), but even without that, it could maybe tell more about where the problem may be.

Volker.

olive_wide — Mon, 20 Jun 2005 10:28:08 GMT

It becomes a terrible problem.Today,I reboot the server 10 times,it hang 7 times!!
The base hardware of the Server is:
Alpha ES45 Model 2
Alpha 21264C,EV68,1250Hz
1024MB*2 memory
Radeon 7500 graphic card.
Openvms 7.3-2
Tomorrow,I will make a crash,and analyze the dump file,show here.

Thanks all.

Olive,

the CLUE output generally does not help in case of forced crashes. Pool and page/swap look o.k.

Your STARTUP process is supposed to hang on the READ from OPA0:

$ ANAL/CRASH sys$system
SDA> SHOW SUMM
SDA> SET PROC/IND=xxx ! pid of hanging process
SDA> SHOW PROC/CHAN

should have busy channel on OPA0:

Volker.

Volker,
Thank you
But I don't know your means :)
Please tell me what shall I do next.It is real a serious bad trouble for me :(

Re: System hang

Volker Halle — Mon, 22 Aug 2005 08:29:38 GMT

Olive,

please issue the commands I've posted in the previous reply. You should see a process named STARTUP, please enter the process-index from column 2 (Indx) from the line with the process name STARTUP.

SDA> SET PROC/IND=xxxx

Then please post the output of the SHOW PROC/CHAN command.

Volker.

PS: Please be aware, that analysing a system hang through this kind of forum may be a long step-by-step process and it may also not lead to a result ! If possible, try to get local consulting from someone experienced in OpenVMS crash analysis.

Sorry, overlooked you specified the data already...
Have you installed the graphics patches? IIRC, there have been issues with this card.
Do you have problems when booting from disk? If not, there might be a problem with code on the CD (which obviously misses the patches :-))
If you have a spare disk (or create a small one on your storage if applacible) and copy the CD onto that, and boot the system standalone from that disk; you may be able to apply the required grphics patches to that system - and booting is likely to be much faster.
It may help.

additional data, from the Graphics 0400 patchkit:

To provide maximum performance, OpenVMS can set certain
RADEON 7500 parameters to optimize bus usage. However,
after extensive testing in multiple configurations, it
was determined that there are some configurations in
which the RADEON 7500 may interact with other devices on
the same bus in such a way as to cause the system to hang
or crash. Therefore, the default settings for the
DECW$RADEON_FAST_DMA environmental option have been
changed as follows:

Just to inform.
