The RAIDWatch manager software provides graphical interface to the
subsystem. Before you can access the RAID system using the software
manager, your must:
1. Create a reserved space on your array(s)
2. Set up the related TCP/IP configurations to enable the Ethernet
port and the http service
3. FTP RAIDWatch program files to the controller IP address
What Is the “Disk Reserved Space?”
RAIDWatch and Reserved Space:
•
There is no need to install the RAIDWatch program to your
management computer if you access the software using the controller
Ethernet port. In order to simplify the installation process, system
firmware already contains important software agents.
•
User’s configuration data and the manager’s main programs are kept in
a small section of disk space on each data drive. The segregated disk
space is called a “Disk Reserved Space.” When configuring a
logical drive, firmware automatically segregates a 256MB of
disk space from each of the member drives.
•
Because the manager’s main program is run from the reserved space on
drives, in the event of RAID controller failure, the manager interface
can “failover” to a counterpart controller. Operators’ access to the
system will not be interrupted.
