NetApp E5700 - Place Controller Offline (Duplex)

Place controller offline (duplex)
If you have a duplex configuration, you must place the affected controller offline so you can safely
remove the failed HIC. You must back up the configuration and collect support data first. Then, you
can take the affected controller offline.
Before you begin
• Your storage array must have two controllers. The controller that you are not placing offline must
be online (in the optimal state).
• You have verified that no volumes are in use or that you have a multipath driver installed on all
hosts using these volumes.
• From SANtricity System Manager, you have verified the details in the Recovery Guru to confirm
that you have a failed HIC and to ensure no other items must be addressed before you can remove
and replace the HIC.
About this task
Perform this task only if your storage array has two controllers (duplex configuration).
Steps
1. From the Details area of the Recovery Guru, determine which of the controller canisters has the
failed HIC.
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 Storage 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.
