What is the status of Hardware at 0/3/1/0.14.104.0.0.0.1

Check from ioscan and what kind of server, OS etc..?

Thansk for your answers.

this hardware is NO_HW:
root@nr0u0253# ioscan -fnH 0/3/1/0.14.104.0.0.0.1
Class I H/W Path Driver S/W State H/W Type Description
===========================================================================
disk 6 0/3/1/0.14.104.0.0.0.1 sdisk NO_HW DEVICE DGC CX700WDR5

it seems that the error is normal ;)
is there a way for delete this entry from ioscan? rmsf is not sufficient.

thanks again for your help.

If you are sure that it is not being used and also check any other devices under same controller from ioscan.

To remove use: rmsf -KH 0/3/1/0.14.104.0.0.0.1

or system reboot will clear automatically.

You are getting these events because event monitor is monitoring some DGC devices which it shouldn't be.

As a work around in the meantime, to stop the events being generated, add the paths of the affected devices to the disabled_instances file:

o Run /etc/opt/resmon/lbin/moncheck to determine the names of instances that should be disabled. (Direct this output to a file.)

o With editor of your choice, Add /delete /modify instances in /var/stm/data/tools/monitor/disabled_instances.
Add a line for each disk or LUN and run monconfig to re-enable monitoring.

Example:

1. Add the following line to the disabled_instances file:

"/storage/events/disks/default/0_3_1_0.14.104.*

Note that a wildcard was used here. "*" this means all devices starting with 0_3_1_0.14.104 will be disabled.

2. Run monconfig: select the "E)nable Monitoring" command, and wait for monitoring to be re-enabled.

3. Do a C)heck monitors. The resource class that you disabled should show up in the list with no description of what to do with events, i.e., there are no monitoring requests.

for the moment i have deleted the NO_HW entry from ioscan (thanks IT_2007).

if the alert comes back, i will look in the resmon's config (thanks HTH).

thanks all.
