Prepare To Add Host Interface Cards - Fujitsu ETERNUS AB Series Maintaining Hardware

Prepare to add host interface cards

You prepare to add host interface cards by backing up the storage array's configuration database, collecting
support data, and stopping host I/O operations. Then, you can power down the controller shelf.
Before you begin
• You have scheduled a downtime maintenance window for this procedure. The power must be off when
you install HICs, so you cannot access data on the storage array until you have successfully completed this
procedure. (In a duplex configuration, both controllers must have the same HIC configuration when they
are powered on.)
Procedure
1. From the Home of SANtricity System Manager, ensure that the storage array has Optimal status.
If the status is not Optimal, use the Recovery Guru or contact technical support to resolve the problem. Do
not continue with this procedure.
2. 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) Open the Enterprise Management Window (EMW) for SANtricity System Manager on your management
station.
b) Select the storage array.
c) Select Tools > Execute Script.
d) Type the following command in the text box.
save storageArray dbmDatabase sourceLocation=onboard contentType=all
file="filename";
In this command, filename is the file path and file name to which you want to save the database.
Enclose the file name in double quotation marks (" "). For example:
file="C:\Program Files\CLI\logs\dbmdata.zip"
This command does not automatically append a file extension to the saved file. You must specify a file
extension when entering the file name.
e) Select Tools > Verify and Execute.
3. 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.
The file is saved in the Downloads folder for your browser with the name support-data.7z.
4. 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.
Attention: Possible data loss – If you continue this procedure while I/O operations are occurring,
the host application might lose access to the data because the storage is not accessible.
5. If the storage array participates in a mirroring relationship, stop all host I/O operations on the secondary
storage array.
6. Wait for any data in cache memory to be written to the drives.
