About Storage Utility
You can use Storage Utility for general maintenance tasks on a stand-alone internal
storage K2 system. Refer to the Service Manual for your K2 product for repair
procedures, such as those required to replace a failed drive. Also refer to
“Storage
Utility” on page 36 for a general description of Storage Utility.
NOTE: Do not run Storage Utility on a shared storage (SAN) K2 client. For shared
storage, run Storage Utility only via the K2 System Configuration application, as
explained in the K2 SAN Installation and Service Manual.
The Storage Utility runs on either the local K2 system or from a Control Point PC. In
both cases the Storage Utility’s primary functionality is hosted by the K2 system. The
Storage Utility uses the connection to the RAID disks for access and configuration.
A stand-alone K2 system runs in either an online mode or an offline mode. These
modes are required for Storage Utility operations. Online/offline modes are as
follows:
• Online mode — This is the stand-alone K2 system’s normal operating mode. When
the stand-alone K2 system is in the online mode and you open Storage Utility, you
can stay in this mode while you view the devices, LUNs, and disks of the internal
storage system, but you can not configure the storage system. However, some
operations are available that do not configure the storage system, such as identify
a drive (flash the drive LEDs), get controller logs, disable a drive, and force a drive
to rebuild.
• Offline mode — In this mode the stand-alone K2 system channels are disconnected
and all media access operations are disabled. You are prompted to put the
stand-alone K2 system into offline mode when you select an operation that
configures the storage system. When the stand-alone K2 system is in the offline
mode you can configure the storage system and perform all Storage Utility
operations. When you exit Storage Utility you can put the stand-alone K2 system
back into online mode.
CAUTION: Use the Storage Utility only as directed by a documented
procedure or by Grass Valley Support. If used improperly, the Storage
Utility can render your K2 system inoperable or result in the loss of all
your media.
Opening Storage Utility
There are two ways to open Storage Utility for work on a stand-alone K2 system, as
explained in the following sections.
Opening Storage Utility through AppCenter
Unless prevented by a system problem, you should always open Storage Utility
through AppCenter. When you do this your AppCenter login permissions are passed
to Storage Utility, so you do not have to log in to Storage Utility separately.
If you are running AppCenter on the local K2 system, as Storage Utility opens it
connects to the storage system of that local K2 system. If you are running AppCenter
on a control point PC, as Storage Utility opens it connects to the storage system of the
K2 system that hosts the channel currently selected in AppCenter.
