3.3 Out-of-Band via Ethernet

The RAIDWatch manager software provides a graphical interface to RAID subsystems. RAID-

Watch comes with an installer program that facilitates the installation of software modules for

local/remote access to the array through standard TCP/IP.

Below is a tree structure of RAIDWatch’s installation options:

Fig. 3.9 Installation Options

If you install RAIDWatch using the “Typical” option or the first two custom modes “Centralized

Management” and “Stand-alone (on Host),” prepare the following:

1. TCP/IP for the network connection to the controller/subsystem’s Ethernet port.

2. Configure a valid IP and appropriate network settings for the RAID subsystem/control-

ler’s Ethernet port.

If you install RAIDWatch using the third installation option, “Stand-alone (on Subsystem),” pre-

pare the following:

1. TCP/IP for the network connection to the subsystem/controller’s Ethernet port.

2. Configure a valid IP and appropriate network settings for the RAID subsystem/control-

ler’s Ethernet port.

3. Array reserved space: If you select the “Custom” installation mode, “Stand-alone (on Sub-

system),” the RAIDWatch installation program will automatically create a reserved space

on the first disk drive and distribute necessary program files to that space.

4. Unless the in-band connection over SCSI host busses is preferred, there is no need to

configure the Peripheral Device setting with the later versions (2.1 and later) of RAID-

Watch manager using Ethernet connection.

NOTICE!

• Only the connections via Ethernet are discussed here.

• Unless you want to start using RAIDWatch under the following conditions, you must not

configure the Peripheral Device settings:

– Using RAIDWatch to access a brand new array that has no configured drive groups.

– Using the In-band method (over the existing host data paths) for array management.

The Peripheral Device settings present the RAID array on the host data paths as if it

is an external device.

If you use an Ethernet link and then unnecessarily configure the Peripheral Device settings,

the application servers will mistakenly identify the RAID array as an external device and

request a driver. Normal RAID array operation does not require supporting drivers.
