Failed I/O Host Card

What Caused the Problem?

An I/O host card in one of the controllers is not functioning properly. The Recovery Guru Details area provides specific information you will need as you follow the recovery steps.

Caution: Electrostatic discharge can damage sensitive components. Always use proper antistatic protection when handling components. Touching components without using a proper ground may damage the equipment.

Important Notes

You will need to replace the controller that has the failed host card. The failed controller is listed in the Details area
If using DHCP configuration on the RAID controller module, before you insert a new RAID controller module into the storage array if needed first update the DHCP server so that it will associate the new RAID controller module's hardware Ethernet (MAC) address with the IP address previously assigned to the removed RAID controller module.

Recovery Steps

If...	Then...
Your storage array has one controller	Go to "Procedure for Storage Arrays with One Controller."
Your storage array has two controllers	Ensure that multipath failover driver is installed and running on all attached hosts. Go to "Procedure for Storage Arrays with Two Controllers."

Procedure for Storage Arrays with One Controller

1	From the Support tab, click the View Storage Array Profile link, and then click the Controllers tab. Check the replacement part number of the affected RAID controller module and ensure that you have a new RAID controller module with the same replacement part number. If you do not have a RAID controller module with the appropriate replacement part number, contact your technical support representative.
2	Stop all I/O to this storage array.
3	Turn off power to all power supply/cooling fan modules in the tray containing the failed RAID controller module.
4	Remove the affected RAID controller module. Refer to the Summary tab to view which management method you are using to manage this storage array. If using DHCP configuration on the RAID controller module, before you insert a new RAID controller module into the storage array if needed first update the DHCP server so that it will associate the new RAID controller module's hardware Ethernet (MAC) address with the IP address previously assigned to the removed RAID controller module.
5	If necessary, insert the battery from the old RAID controller module into the new replacement RAID controller module. Consult your hardware documentation for details. Make sure at least 1 minute has elapsed. Then, insert the new (compatible) RAID controller module firmly into place.
6	Turn on power to all power supply/cooling fan modules in the tray. Wait until all drives have completed the spin-up process, and then go to step 7.
7	From the Support tab, click the View Storage Array Profile link, and then click the Controllers tab. Check the status of the RAID controller module. The RAID controller module should have an Optimal status.
8	Click the Recheck button to rerun the Recovery Guru. The failure should no longer appear in the Summary area. If the failure appears again, contact your technical support representative.

Procedure for Storage Arrays with Two Controllers

Place the affected controller offline.

a	From the Support tab, click the Manage Controllers link.
b	Click the Place Controller Online or Offline link.
c	Place the affected controller Offline.

Read all of the following steps before taking any action.

a	Click the Recheck button to rerun the Recovery Guru.
b	Select the Offline Controller problem that is being reported in the Summary area.
c	Complete the Recovery Steps in the Offline Controller problem to replace the controller.
