Netfinity Manager 5.0 and above

Through Netfinity Manager 5.0 and above, data scrubbing can be performed via synchronization as a background task while users access the data. Netfinity Manager supports either local or remote access on the server console under OS/2 or NT. Synchronization can be scheduled to run at off-peak hours without requiring user intervention by using Netfinity's event scheduler. To use Netfinity 5.0 to schedule data scrubbing, download NF50RAID.EXE from:

http://www.us.pc.ibm.com/files.html

This file contains updated Netfinity program files that are required for scheduling data scrubbing on adapters or controllers with the write policy set to write-back cache.

When the Netfinity Manager code is installed, the following operating systems are affected:

•  OS/2
•  WINNT
•  WIN95.

System administrators can also use Netfinity Manager's out of band, or serial connection, capabilities to dial into a machine that has Netfinity Manager installed, and access the entire network. This 'out of band' support is particularly important since this allows LAN administrators to 'dial in' from remote locations to initiate an array synchronization. All these features, plus many more, are discussed in the Netfinity Manager Users Guide.

Netfinity Manager 5.0 and above is included in ServerGuide version 3.1 and above, which is shipped with every IBM server.

If you have ServerGuide version 3.0 or older, you can obtain an upgrade at no additional cost to the latest release.

Instructions for Configuring ServeRAID Adapter Under Netfinity Manager 5.0:

•  Run ServeRAID Manager service
•  Choose Options from the menu bar.
•  Choose Configure Enclosure.
•  Configure the adapter number and channel for each bank using  the IBM ServeRAID Administration and Monitoring Utility.
•  Choose Options / Save Configuration.

Instructions for Scheduling Data Scrubbing:

1.  Start the Netfinity Service Manager.
2.  Select Event Scheduler.
3.  Choose New.
4.  Type in DATA SCRUB for the new event name or any specific name you choose.
5.  Highlight Synchronize All ServeRAID Drives under Tasks.
6.  Select Systems or Groups under Scheduled By  to choose the systems for data scrubbing.

   Note:  Ensure that all systems selected have an ServeRAID adapter installed that  supports the Netfinity Manager 5.0 data scrubbing utility. See the above  compatibility matrix for supported adapters.

7.  Once all systems have been selected, select Schedule   to choose the time and date along with the frequency desired. IBM  recommends weekly data scrubbing for a high level of data protection.
8.  Select Save to save the event and exit.

Note: The status of the DATA SCRUB event can be viewed by clicking on View Logs within the Event Scheduler. If the log displays that the DATA SCRUB event has started but has not yet been completed, the percentage complete can be viewed in the ServeRAID Monitor portion of Netfinity Manager.

In addition, the ServeRAID adapters provide two other methods for initiating data scrubbing. The TCP/IP based client/server administration utility allows online synchronization of arrays initiated from a Windows 95 or Windows NT client station.
