Replace Failed Host Interface Card; Place The Controller Shelf Offline - Fujitsu ETERNUS AB Series Hardware Maintenance Manual

d) If only some of the volumes are returned to their preferred owners after auto-distribution or manual
distribution you must check the recovery guru for host connectivity issues.
e) If there is no recovery guru present or if following the recovery guru steps the volumes are still not
returned to their preferred owners contact support.
6. Collect support data for your storage array using SANtricity System Manager.
a. Select Support > Support Center > Diagnostics.
b. Select Collect Support Data.
c. Click Collect.

Results
The process of upgrading a host interface card in your storage array is complete. You can resume normal
operations.

Replace failed host interface card

You replace a failed host interface card (HIC) with a new one.
About this task
• When you replace a failed HIC, you must power off the storage array, replace the HIC, and reapply power.
Attention: Possible loss of data access – Never install a HIC in an AB6100 controller canister if that
HIC was designed for another ETERNUS AB controller. In addition both controllers and both HICs must
be identical. The presence of incompatible or mismatched HICs causes the controllers to lock down
when you apply power.

Place the controller shelf offline

You must place the controller shelf offline so you can safely replace the HICs. You must back up the
configuration and collect support data first. Then, you can take the controller shelf offline.
Before you begin
• You have scheduled a downtime maintenance window for this procedure. You cannot access data on the
storage array until you have successfully completed this procedure. Because both controllers must have the
same HIC configuration when they are powered on, the power must be off when you install HICs.
Procedure
1. Back up the storage array's configuration database.
If a problem occurs when you remove a controller, you can use the saved file to restore your configuration.
a) In System Manager, navigate to the support page.
b) Select the Support Center tab.
c) Select Diagnostics tab.
d) Select Collect Support Data.
2. Ensure that no I/O operations are occurring between the storage array and all connected hosts. For
example, you can perform these steps:
• Stop all processes that involve the LUNs mapped from the storage to the hosts.
• Ensure that no applications are writing data to any LUNs mapped from the storage to the hosts.
• Unmount all file systems associated with volumes on the array.
Note: The exact steps to stop host I/O operations depend on the host operating system and the
configuration, which are beyond the scope of these instructions. If you are not sure how to stop host I/O
operations in your environment, consider shutting down the host.
