Every day, at about the same time, we receive an EMS error that we've lost connectivity to our EMC CX500 storage array which is connected via 2 GB fibre to our two 9000 servers. Only one box gets the error.
The error states a 'Device connectivity or Hardware error' with a discription of 'the device is not in a state where it can process requests. Manual intervention is required'.
We've gone thru the recommended actions--
We've replaced the adapters and the fibre to the array;
The error messages assume (wrongly) that it is attached via a SCSI bus, and most of the 'probalbe Cause/Recommended action' items really don't seem to apply.
Also, we haven't received any application errors, etc, as a result of this.
Any ideas welcomed.

Re: EMS device connectivity errors daily with EMC array
Now see if you still get the errors.

Re: EMS device connectivity errors daily with EMC array
HP has an article on how to do this:
http://www2.itrc.hp.com/service/cki/docDisplay.do?docLocale=en_US&docId=200000077093864
I use a wildcard to disable all instances down the Fabric Ports where the Clariion is connected.

Re: EMS device connectivity errors daily with EMC array
You have an old version of the OnlineDiags; A.38.00 is the HWE0303 release.
The problem with EMC devices being unnecessarily monitored was fixed in the HWE0309 release (A.42.00). CR JAGae75278 covered this.
You should install the latest version of OnlineDiags, which is currently HWE0412, A.47.00, and the latest patch for that version, which is PHSS_32492
You can get the latest version from http://www.software.hp.com/portal/swdepot/displayProductInfo.do?productNumber=B6191AAE
The work-around until you can do this is to use the 'disabled_instances' file (t
he document Bill references describes how to do this). The effect of this worka
round is to prevent any Events being generated for the specified paths; the moni
tor is still actually monitoring the devices.

SolutionCheck for which LUN is most busy and does it gives any errors in /var/adm/syslog.log
In glance which LUN is being used heavily. Disable bad block relocation on the LV as Array takes care of that automatically.
Please post your error message in EMS and ccheck dmesg For LUN switch or something like that.

Re: EMS device connectivity errors daily with EMC array
Did you upgrade the OnlineDiags, as recommended, and did this fix the problem?
