Re: HSG80 ERROR PLEASE HELP.

You might want to provide just a little more information about your environment...

Where are you getting that error ?

Cheers,

Re: HSG80 ERROR PLEASE HELP.


Hi Rob,

Thanks, This error is an atomatic alert from SWCWDSOPSPROD01.cw.uk.azp>>- SWCWDSOPSPROD01.ukcw.xxxx.net HSG80 11000000000 HSG80 disksdisk41500.1 >NSMTEC>1229525841.1.1>NODE TIME>Dec 17 14:10:40.

This alert is from Host end.Its connected to HSG80. In HSG80 events I cannot find any warnings. No failed disk are showing.Host are online.


Unix team told me this certainly in some days a drive is going to be failed, so this might be a early warning, but I am not sure abt that.

Re: HSG80 ERROR PLEASE HELP.

Again, that tells us little about the environment...

What is the hardware configuration ?

A "SHOW DISK41500" from the HSG80 might be useful to see.

Re: HSG80 ERROR PLEASE HELP.

I'm guessing this error is from SWCC. I've seen something similar from SWCC running on our old VMS Servers monitoring HSD Controllers.

In our case it's correctly reported problems where the controller has gone offline.

Again, just guessing, in this case it's either the disk or one of the paths to the disk that's causing problems. The monitor on the server is detecting that it can no longer communicate with the device.

More detail on how the HSGs are connected to the server might help. Are there multiple paths etc.

Hi,

> Reported PORT_ID = 5000-1FE1-000B-4754
> PORT_2_TOPOLOGY = OFFLINE (offline)

This looks like it *might* be the problem...

I'll guess that you might have a SAN switch down, but again as you've failed to give us any details on the hardware configuration, that's complete speculation...

Cheers,

Rob

Re: HSG80 ERROR PLEASE HELP.

No, it means that the port has never been configured or manually been disabled:
CLI> SET THIS_CONTROLLER PORT_2_TOPOLOGY = OFFLINE

A disconnected link looks like this:
PORT_1_TOPOLOGY = FABRIC (connection down)

Re: HSG80 ERROR PLEASE HELP.

hi,

as for the disk , at least it's a spare disk. has it any error lights on the drive ?
if you 'run fmu' on the hsg80 what does the last error say 'show last most' ?
