1.0 Updates from Netfinity Fibre Channel RAID Support Version 2.1
(Symplicity 6.22)
____________________________________________________________________________________________
The IBM Netfinity Fibre Channel Storage Manager v7.0 is a Java-based tool
for managing Netfinity Fibre Channel storage products. The new interface
has a similar look-and-feel to ServeRAID (PCI RAID) management for an easier
transition from one to the other.
1.1 New Features
____________________________________________________________________________________________
The new Java-based IBM Netfinity Fibre Channel Storage Manager offers:
- An easy-to-use management console with intuitive graphical interface
- The ability to build shared storage configurations using Storage
Partitioning
- Firmware enhancements designed to help you manage your Fibre
Channel-based storage
Java-based implementation simplifies management of Netfinity Fibre Channel
Storage Subsystems with:
- User-friendly fly-over help on new features and capabilities
- Graphical depiction of physical storage subsystem(s)
- Automatic device discovery and one-button configuration to
reduce the complexity of setting up and configuring the RAID
storage subsystem
- Remote management capabilities for administration of the
Netfinity Fibre Channel Storage Subsystem through corporate firewalls
Storage Partitioning is a compelling new feature that allows you to
consolidate data storage from multiple servers to a single storage RAID
Array subsystem. Storage Partitioning benefits include:
- Support for up to four (4) independent hosts enabling the sharing
of a single storage
resource.(key for implementing storage consolidation
and for improving overall system performance)
- Overall storage management cost reductions by creating "pools"
of available shared storage that can be dynamically allocated
on a server-by-server basis
New firmware features include:
- Support for up to 32 logical units (using Windows NT with
Service Pack 5), which offers much greater flexibility in configuring
large storage arrays
- Background data scrubbing, designed to detect and recover from
physical storage media problems before they become a problem
at the time a recovery is needed.

The following are firmware and NVSRAM files necessary for IBM Netfinity
Fibre Channel Storage Manager 7.

firmware_03010003.dlp IBM Netfinity Fibre Channel RAID Controller Migration
Firmware Package
NV4766WNT856002.dlp IBM Netfinity Fibre Channel RAID Controller NVSRAM
Package
NOTE: The firmware packages (*.dlp) contain both bootware and appware and
replace the separate packages in previous versions of firmware.
The following are script files necessary for IBM Netfinity Fibre Channel
Storage Manager 7. These files change NVSRAM settings in the User
Configurable Area of NVRAM based on special criteria. This area is used
to make changes that might be required by a user to satisfy different
Operating environments.
networkon.scr Enables direct networking to IBM Netfinity FC RAID Controllers
networkoff.scr Disables direct networking to IBM Netfinity FC RAID Controllers
reseton.scr Enables propagated reset for Microsoft Clustering environments
to IBM Netfinity RAID Controllers
resetoff.scr Disables propagated reset for Microsoft Clustering environments
to IBM Netfinity RAID Controllers
softreseton.scr Enables soft reset setting to IBM Netfinity FC RAID Controllers
for Microsoft Clustering environments
softresetoff.scr Disables soft reset setting to IBM Netfinity FC RAID Controllers for
Microsoft Clustering environments
To execute the script files, users must use the Netfinity Fibre Channel
Storage Manager Script Tool Option from the Enterprise Mananagement Tools
Menu and choose Editor. You can then load the appropriate script file and run.
Users may also modify individual NVSRAM Bytes for specific operating systems.
For example, if you are using SCO UnixWare 7 or Netware and want only those
LUNs that actually exist to be displayed in the initial scan - With the bytes
at location x11 and x24 (x = hex) set to the default ship value of 00, NT, SCO,
and Netware work properly but SCO and Netware will show more LUNs in their scan
than are actually present. You will only be able to use the real ones and will
get an error if you try to use the others. This is not normally a concern
but is presented for those who might like to change this behavior. By changing
offset x24 to x7F, you will only see the actual LUNs. An example of what you
would see in the scan for this case with the default values is in order. If
you have 1 storage subsystem with dual controllers and each controller is in
active mode with controller A having 2 LUNs and controller B having 1 LUN then
when controller A is interrogated, it will report that it has 2 LUNs. It will
also report that it sees 1 LUN on controller B. So the OS (SCO or Netware) will
then show 3 LUNs for this. When controller B is asked, it will report its one
LUN and 2 for controller A. This again is 3 to the OS. In the system scan
report there will be 6 LUNs reported. Once you have defined the real drives
to the OS such as SDIADD in SCO, then this would no longer be a problem.
NOTE: Do not change the values from 00 for an NT host.
You may need to set offset 0x1c to hex a4 for SCO. For more information
please refer to the IBM Netfinity support website.
2.0 Installing IBM Netfinity Fibre Channel Storage Manager Updates
____________________________________________________________________________________________
Before following steps listed in the IBM Netfinity Fibre Channel Storage Manager
Installation and Support Guide for Windows, refer to this section for any
updates.
2.1 Migration from 6.22
____________________________________________________________________________________________
In Chapter 3 of IBM Netfinity Fibre Channel Storage Manager Installation and
Support Guide for Windows NT, Installing Software in a Standard Configuration,
the following changes have been made:
1. Prior to "Install SM7 Migrate" listed on Page 39, add:
a. Stop the Disk Array Monitor from the Windows NT Services
b. Change Disk Array Monitor Startup Options from Automatic to Manual
2. After "Upgrade Firmware" and Prior to "Complete the Installation"
on page 39,add:
a. Change Disk Array Monitor Startup Options back to Automatic from Manual
b. Start Disk Array Monitor service
3.0 Helpful Hints
____________________________________________________________________________________________
The following are some helpful hints when using IBM Netfinity Fibre Channel
Storage Manager 7.
1. There is a connector on the back of the storage subsystem above
the serial connectors labeled UPS/GPIO. This connector is used for
UPS support. More information will be available at a later date to
describe the settings and support for this. Please check the website
for this information.
2. If you are removing the subsystem from service, it is strongly
recommended that the configuration be removed from the disk drives.
This can be done by using a 'Reset Configuration' option to delete
the configuration information on the drives.This will leave you
with the default LUN 0 which you then should delete. Shutdown the
controller(s) and drives and remove the drives. Do not restart the
controllers again with the drives attached as this will create the
default LUN 0 again.
3. In addition to the possible cases of accidentally removing or
failing a good drive you should also be aware that this procedure to
revive the drive (see IBM Netfinity Fibre Channel Storage Manager Help
Pages on Recovery Options and the section 'Manual Recovery Options')
may need to be used on a drive where automatic copyback from a hotspare
did not occur.
4. When implementing clustering environments, it is important that you
do NOT set a preferred owner for either the cluster group or the quorum
resource.
5. If you need to shutdown either server in a clustered environment,
you MUST transfer all resources from that node, to the node which is
to remain online BEFORE invoking shutdown. If you are installing
software on a machine in a production clustered environment, be aware
of the potential for the installation process to automatically shutdown
or reboot the machine. Ensure that all resources are transferred away
from the machine on which software is being installed, if the
possibility exists that the installation will reset the machine.
Stop Clustering Service on the server to be shutdown.
