Hi,

As indicated in the log event page, the event code is 385 which signifies the event description given.

There is a I2C bus inside the array which has various sensors to monitor the status of the array components like tempreture sensor etc. One of the such devices is not appreantly working thus not coommunicating over the I2C bus. This error is being reported by the controller M/C1 firmware.

Refer the following array controller log document at
http://h20000.www2.hp.com/bc/docs/support/SupportManual/lpg60194/lpg60194.pdf

As mentioned in the above document, the suspected components are Controller, power supply, battery, midplane.

I would check the all FRUs status with special eye on FRU indicated in the log event page (FRU Location = M
FRU Data = enclosureId/slot/component/subcomponent :
0x00/0xff/0xff/0xff )
using
1. CommandView SDM array/component status
2. Using armdsp -a /armdsp -f commands
3. Using vfpdsp/vfpdsp -f commands.

This would help to identify the FRU.

Wish,

These kind of events are NO problem when you see these once or twice a day. Please disregard them. The following events may also be logged intermittently:

BATT_CHGR_COM_EVENT_EH
CHGR_PIC_RESET_EH
JBOD_SPEED_CHANGE_ATTEMPT_EH

Hi Wish,
The above mentioned error doesn't require any action - this is a normal if it is appearing once or twice per day.
We are having 1 VA boxes, which is used to reports the same.

You may check the status with

#armdsp -s
#armdsp -a
#armlog -e -t

( here is the starting date )

For getting detailed diagnose output you can use following

# armdiag -I -if /tmp/armdiag_date

Try to do when there is not that much load.

The all above commands to be used on the server, where commandview is installed.

Regards,

Shameer
