This error does not look like an EMS issue, but a bad SCSI device or non/badly terminated device.

Make sure that your device chain is terminated with the proper terminator, not over sized (too many devices, cable length in chain should be less than 3M)

This can be cause by a drive about to fail also, but not quite as common.

Regards,
Shannon

I ugene,
where did you get taht information???

Re: EMS issue

Paul Sperry — Fri, 14 Feb 2003 21:40:59 GMT

check your cabling and termination

The "lbolt" message in general means the driver is not able to complete the operation or IO in the given time. The device cb012000 (cb in decimel is 203 ie the sctl driver .. from lsdev command), so I'm guessing this is probably a tape device of some sort autoloader or autochanger (on c1t2d0). You should not disable the EMS yet until you know for sure the hardware having problem commnunicating with EMS.

Eugeny Brychkov — Fri, 14 Feb 2003 21:43:23 GMT

It's secret :o)
The general idea is first to check that you have system well patched with Diags, GR and HWE patch bundles from the same CD revision, and check for hardware issues (as Shannon mentioned): cables, terminators....
BTW, what's this device (attach 'ioscan -fn')? If you have multiple devices on the bus (c1) and only this shows such behavior maybe device is misbehaving?

how do I remove those no HW device...i tried rmsf -H ...
and it doesnt' work

Re: EMS issue

Eugeny Brychkov — Fri, 14 Feb 2003 22:13:01 GMT

These NO_HW devices are not those we troubleshooting right now (reboot will solve this issue). Where're 'ioscan -fn' and 'ioscan -fnC ctl' asked for?

Re: EMS issue

S.K. Chan — Fri, 14 Feb 2003 22:33:32 GMT

So it's an optical drive then ..have you installed the latest "SCSI IO Subsystem Cumulative Patch" on your system. If I am not mistaken this could be a patch issue.

Re: EMS issue

hi, it is the optical drive...how do I check if the patch is installed on the ssytem???

S.K. Chan — Fri, 14 Feb 2003 22:45:36 GMT

Depending on your OS .. for 11i the patch you need is PHKL_28096. For 11.00 it's PHKL_28131. Double check it in ITRC and make sure all dependency patches are loaded as well (if any). To check for existing patch for example ..
# swlist -l patch | grep PHKL_28096

Re: EMS issue

hpuxhelp — Fri, 14 Feb 2003 22:46:46 GMT

the O/S is 10.20

Re: EMS issue

S.K. Chan — Fri, 14 Feb 2003 23:02:05 GMT

That would be ..
PHKL_26398 (s800 10.20 SCSI cumulative patch)
