EXTENDED SENSE DATA RECEIVED

[Joewee]

Hi All,


Please find the error below. I know that this is a normal error and it can be ignored on a normal working condition. But my concern is, this error is coming very often. In the past few hours we received 13 times the same error. kindly suggest me what is supposed to be done on this.

All these disks are connected to once controller redundent pair which are HSZ70 type. Should this be some problem on the controller side. All the above error are logged in a span of few hours only.

[Jur van der Burg]

Use DECEVENT to decode the error. It's a unit attention with ASC A1 / ASQ 11 which comes from the controller. And check the other disks as well, it could be one bad disk hanging up the bus.

Jur.

[Wim Van den Wyngaert]

$ anal/disk/read xxx for the device.

If parity errors are shown, you have bad blocks on disk. You can try to mark the bad file as "set file/nomove" and replace it by a good file from another system.

If no parity errors are shown, the disk probably recovered well.

New disk sometimes give the errors during a few days and then it stops giving the error. Also when previous free space is allocated the first time you can encounter the error.

Advice : always protect your data with shadowing or raid.

hi,

if you can get on to the storage controllers try 'run fmu' and do a 'show last most' command to display most recent error.

[Joewee]

Hi Mark,

Please find the FMU out put. But nothing latest was there.

Hi Wim,

Ana/disk/read is in progress.


Hi Jur,

Im not sure how to decode the error with the decevent.

cany you help me with that please?




Thanks for all your replies.


Regards,
Joe

[Volker Halle]

Joe,

DECevent is an HP analysis tool and can be downloaded and installed on your OpenVMS system.

http://h18023.www1.hp.com/support/svctools/decevent/index.html

Volker.

[Volker Halle · Accepted solution]

Joe,

note that you can also install DECevent on a Windows System and run the OpenVMS ERRLOG.SYS analysis under Windows.

See the DECevent home page...

Volker.

[Joewee]

Volker,

Many thanks. I will check the same now.

Wil keep you all updated.

thanks
Joe

[Wim Van den Wyngaert]

fmu show last all full could show even more info.

Wim

Wim,

Thanks and

ana/disk/read gave only the warning.

Any suggestiond on this.

[Joewee]

And i noticed one more think now.

FMU> exit

FMU -- Normal termination, status: 1.
Power Supply failure detected.
Fan failure cleared.

HSZ019>


I cleared this message through

> clear cli

but it popped up again.

This could be the problem for this?

[marsh_1]

hi,

try clear cli again , if it pops up again can you run fmu again and do show parameters

[Richard Brodie_1]

ASC A1 / ASCQ 11 is indeed "fan fault is fixed". I would pull the other ASC/ASCQ pairs, and see what else shows up. Even without DECevent, they are easy enough to read off.

[Volker Halle]

Joe,

in a previous entry I wrote:

'note that you can also install DECevent on a Windows System and run the OpenVMS ERRLOG.SYS analysis under Windows.'

I was apparently thinking of WEBES SEA (System Event Analyzer), where you can do exactly this.

After scanning the DECevent NT user guide, I'm not sure, that you can actually analyze OpenVMS Alpha ERRLOG.SYS files with this tool under Windows.

Volker.

[Joewee]

Mark,

I cleared again and it haven came back. I was monitoring the same for quite some time now but it haven popped out.

Richard,

Im not sure of what is "ASC/ASCQ", Should I have to do anything physicall for this??

Volker,

Thanks, I tried to install it on windows but it said some file was missing and dont have much rights on this PC so i left it there itself.


All,

Now there were no more errors on any of the disks. But still out of my curiousity i would like to know that, what made the disks to log so much of errors in that short span of time. And what can be done to prevent it in the future if possible.

Thanks for all your replies.


Joe.

[Richard Brodie_1]

ASC Additional sense code
ASCQ Additional sense code qualifier

This is SCSI standards speak for error code/subcode. Jur pulled these out using DECevent but your original report is
smart enough to decode the ASC at least as:

SENSE CODE = A1(X)

You can find the ASC/ASCQ values in the raw data: 12th and 13th bytes of the data block returned.

EXTENDED SENSE 00060070
98000000
00000000
000011A1
^ ^
ASCQ ASC

If you see other codes you can look them up in the service guide: http://h18004.www1.hp.com/products/storageworks/techdoc/controllers/EK-HSZ70-SV-B01.html

[Wim Van den Wyngaert]

My guess is that the first write gave "extended sense". Thus a rewrite was done and this worked. Did the disk move the block to the bad block list or did the rewrite worked better than the first write ?

My expierence is that often a range of bad blocks is found. And as long as blocks are allocated from this range, you have the problem.

fwiw
