Replacing a hard disk drive
The server contains two hard disk drives (HDDs). The HDDs are eld replaceable when
directed by Hitachi Vantara customer support.
Before you begin
Obtain the new HDD or HDDs.
Before you replace a hard disk drive, be sure you understand the following points:
■
Do not attempt to replace an HDD unless you are instructed to do so by Hitachi
Vantara customer support.
■
Failed hard disks are hot-swappable, so a failed hard disk can be replaced without
shutting down the server. However, there are serious risks in trying to swap a drive
that is not failed.
■
Disk redundancy is unsupported while the disk is removed from the server.
