IBM SSA RAID Adapters for PC Servers
SSA Windows NT Server 4.0 Device Driver
Installation / Upgrade Process - README.TXT
Version v1.09 - Last Updated 16th December 1999


NOTE: To create a device driver install diskette, copy all the
      files in this directory to a floppy diskette. When prompted
      below, enter path as a:\

NOTE: If you wish to install Windows NT onto an SSA resource
      attached to the IBM Advanced SerialRAID/X Adapter please
      follow the instructions provided in the readme.txt file
      contained in the \ntboot subdirectory of this package.

Follow the steps below to install :

1) If not upgrading an existing driver go to 2) otherwise,

   To manually check the version of the device driver you are
   currently running open Windows NT Explorer at :

   :\winnt\system32\drivers

   Right click on the file ibmssa.sys and select properties, and
   view the Version tab. Select the "Internal Name" field, and
   note the date.

   Repeat this process with the latest version in this directory,
   or on a diskette created from the Web site.

   If the version in the \winnt\system32\drivers directory is
   older, you should continue with step 2. Otherwise you need do
   nothing.

   IBMDSK.SYS
   ----------

   Please note you no longer require the ibmdsk.sys device driver.
   This was installed by the SSA device driver diskettes version
   1.01 to 1.06. The driver, and its references will be removed
   from your system when you install the new driver for your
   adapter. You may need to remove the entry from the SCSI
   Adapters, "Drivers" tab after you restart your system. The file
   itself can also be removed from the above drivers directory.

   To upgrade the driver follow the steps in 2)


2) Open the Control Panel and select SCSI Adapters.

   Select the drivers tab and click "Add".

   Click "Have Disk", when prompted with the a:\ path, insert the
   Windows NT Device Driver diskette, or enter the path, where you
   extracted this package to, usually :

      c:\issa\update\driver

   *** Users with the "IBM SSA RAID Cluster Adapter" should read
       the section "IBM SSA RAID CLUSTER USERS" below before
       proceeding ***

   Select the appropriate adapter - if you have more than one SSA
   adapter type in this host select any one of them. Answer "New"
   if asked which driver you wish to use.  When completed answer
   YES to reboot.

   NOTE: If you have more than one adapter in the same server, all
         SSA adapters will appear to Windows NT as the type you
         selected during install. This does not matter as they all
         use the same device driver but "IBM SSA RAID Cluster
         Adapter" users MUST follow the instructions below.

3) You should now install the updated version of the SSA Event
   Logger by running

      c:\issa\update\evnlog\setup.exe

   The latest version of RSM can be downloaded from the SSA
   Customer Support Homepage.

************************************************
IBM SSA RAID CLUSTER ADAPTER USERS - PLEASE NOTE
************************************************

If installing the "IBM SSA RAID Cluster Adapter" please note :

  NON-CLUSTER MODE (1-way)
  ================

  Even if you have other SSA adapters in the server, select the
  following adapter when prompted by Windows :

     "IBM SSA RAID Cluster Adapter - Adapter A"

  CLUSTER MODE USERS PLEASE NOTE (2-way)
  ==============================

  When two IBM SSA RAID Cluster Adapters are connected via SSA
  loops in what is called "2-way cluster mode" you MUST install
  each adapter in a separate host server. Each adapter must be
  given a node number, either A or B.

  When prompted by Windows install one adapter in the cluster as:

     "IBM SSA RAID Cluster Adapter - Adapter A"

  and the corresponding cluster partner adapter in the other
  server as:

     "IBM SSA RAID Cluster Adapter - Adapter B"

  even if you have other SSA adapter types in the server.

  NOTE : IF YOU DO NOT DO THIS THE CLUSTER WILL NOT FUNCTION
         CORRECTLY

  Note : If you have more than one "IBM SSA RAID Cluster Adapter"
         in a host it cannot be connected by means of SSA cables
         to another "IBM SSA RAID Cluster Adapter" in the same
         host.

  You must install a new NT Service using issaclus.exe, which is
  distributed from the SSA Customer Support Homepage with the NT
  Driver package for the SSA RAID Cluster Adapter (LL10). To do
  this copy ISSACLUS.EXE to :\issa. In
  :\issa execute the following:

       issaclus -install
       net start issaclus

  This will install and then start issaclus as an NT Service. It
  will be automatically restarted whenever NT is restarted.
