4 Attention: If your system is powered on and performing I/O operations, go the management GUI and
4 follow the fix procedures. Performing the replacement actions without the assistance of the fix procedures
can result in loss of data or access to data.
4
Even though many of these procedures are hot-swappable, these procedures are intended to be used only
4
when your system is not up and running and performing I/O operations. Unless your system is offline,
4
4 go to the management GUI and follow the fix procedures.
Be careful when you are replacing the hardware components that are located in the back of the system
4
4 that you do not inadvertently disturb or remove any cables that you are not instructed to remove.
Ensure that you are aware of the procedures for handling static-sensitive devices before you remove the
4
4 enclosure.
Note: If your system is online, replacing an expansion enclosure can cause one or more of your volumes
4
4 to go offline or your quorum disks to be inaccessible. Before you proceed with these procedures, verify
which volumes might go offline. From the management GUI, go to Home → Manage Devices. Select the
4
enclosure that you want to replace. Then select Show Dependent Volumes in the Actions menu.
