Maintenance procedures using Grass Valley
Storage Utility

Several maintenance procedures can be performed using the Grass Valley Storage
Utility.

To perform the following tasks, refer to the K2 Storage System Instruction Manual:

• Checking RAID controller microcode version

• Loading RAID controller microcode

• Identifying disk modules prior to removal

• Downloading K2 Lx0 Expansion disk drive firmware

• Disabling a K2 Lx0 Expansion RAID controller for removal

• Disabling a K2 Lx0 Expansion disk module for removal

• Configuring K2 Lx0 Expansion network and SNMP settings

Monitoring K2 Lx0 External RAID status using
NetCentral

You can monitor K2 Lx0 External RAID Storage systems using Grass Valley’s
NetCentral monitoring software. Enabled by SNMP, NetCentral can continuously
monitor the storage system and send notifications if there is a problem. The SNMP
agent software required for NetCentral monitoring resides on the RAID storage
device itself. As a result, the K2 Lx0 External RAID appears in NetCentral as a
standalone device rather than as a subsystem of the K2 Media Client.
