Once you have selected an adapter, you can view the attached SSA resources from a selection of logical and physical views. All of which lead to individual resource views which provide the actions to configure and maintain your SSA resources.
The Adapter View displays the VPD of the selected adapter and provides the actions available to the user.
Note: | The actions displayed correspond to the functions that are available for the given adapter. |
The Check Code Level action provides a method to check the level (ROS) of adapter microcode running on the selected adapter.
Adapter Vital Product Data (VPD) Attributes:
Product Number: Eight-character part number of the adapter.
FRU Part Number: Eight-character part number of the field-replaceable unit.
Serial Number: Unique serial number identifier of this adapter.
Eng. Change level: Ten-character identifier of adapter release version.
Manf Location: Six-character field containing the IBM plant of manufacture.
ROS Level: Eight-character field containing the current adapter firmware level. This can be updated to the latest level with the help of the CheckLevel action described below.
Loadable Microcode Level: Also known as the LL Field. Two-digit field containing type of SSA adapter. This is the type of adapter firmware you should apply to this adapter using the supplied download utilities.
Device Driver Level: Two-digit field that describes the type of device driver that is required for this adapter. Currently always 00.
Desc. Function:
DRAM Size: DRAM=XXX shows the size, in Mega-Bytes, of the data RAM installed on the adapter.
Fast Write Cache Size: CACHE=XXX shows the size, in Mega-Bytes, of the Fast Write Cache memory installed on the adapter.
RSM Page Layout:
The RSM page layout is designed around the Netfinity Web Services format.
The left hand frame, the explorer frame,
contains an expandable tree of SSA adapters and their resources.
The resources are grouped by resource type. The common navigation frame, above the
explorer frame contains links to the RSM functions which are
available from every RSM page. The right hand frame, the configuration frame, contains several
sub-areas. The style of each sub-area is constant throughout RSM. The navigation area contains a links to the main
RSM resource views; System View,
Logical View, Physical View,
and Enclosure View. It also contains a
logically back button, and a link to the relevant help page.
You must first select an adapter from the Adapter List
page before you can select any of the Logical, Physical, or Enclosure Views.
If you have not yet selected an adapter, the buttons will be greyed out.
Logically back means to go back one logical step. For example,
if you are in the middle of creating an array (a procedure that contains
several steps), and you select the logically back button, you
will return to the page where you selected Create Array.
Note:
The information area contains reports of user errors, warnings, and (after some actions) important information . These messages appear only once. For example, if you are in a Resource View, and select FlashOn for the resource, a message appears to verify that the resource if flashing. When you move elsewhere, the message disappears. It does not reappear, although the resource may still be flashing.
The title area contains links to other Views and CheckLevels (where appropriate). The page title contains the name of the resource you are configuring or viewing (for example, an adapter or drive serial number).
The configuration area contains the relevant details for the resource that you are observing. It also contains user input forms (where appropraite).
The actions area contains all the actions you can perform on or with the resource that you are viewing.
Actions:
Navigation Actions:
The SSA Remote Systems Management icon is a link back to the Adapter List page - exept on the Adapter List page itself, where the icon will refresh the page. The Help icon opens a new browser window which contains context sensitive help information. The help icon will be shown if the relevant help file is accessible, that is, is in the required location. The Logical View icon, in the navigation
area, links to a logical view of the SSA subsystem. The current SSA resources, as
seen by this adapter, are grouped by array type and disk usage. Any resource types,
visible to, but not supported by this adapter can be grouped
under the categories 'Unsupported', 'Pre-configured', 'System (AIX)'
1 or 'System (PC)'
2
You can only access the Logical View after you have selected an adapter from the
adapter list. If you have not selected an adapter the icon will appear grey - as shown
left. Select the appropriate adapter serial number from the
Explorer Frame or Adapter List. You can only access the Physical View after you have selected an adapter from the
adapter list. If you have not selected an adapter the icon will appear grey - as shown
left. Select the appropriate adapter serial number from the
Explorer Frame or Adapter List. The Enclosure View icon, in the navigation
area, links to a list of enclosures connected to this adapter, by SSA cables. The enclosures
must support SCSI Enclosure Services. Currently only IBM 7133 Models D40 and T40
You can access the Enclosure View only after you have selected an adapter from the Adapter List. If you have not selected an adapter the icon will appear grey - as shown left. Select the appropriate adapter serial number from the Explorer Frame or Adapter List. The Logical Back icon links to the previous page in the RSM page hierarchy. This may not always be the same pagewhich was viewed before the current page. For example, the previous page when the current page is the Resource List is the Logical View.
The Physical View icon, in the navigation
area, links to a physical view of the SSA subsystem. The disk drives, and other adapters
when running cluster configurations are shown as they are connected to this adapter.
Information Area
All error, warning and information messages are diplayed in the Information Area. The type of information is defined by the icons:
The information is only displayed once. It will not be displayed again if any other action is selected, including refresh. Multiple error, warning or information messages will be displayed one after another. The information area is providid by the Netfinity SM nhttp class (The Netfinity HTML library).

Information Icon
Configuration Area
This section contains all the information relating to the currently selected SSA Subsystem resource. When an action has been selected, this area may contain a form. The fields correspond to the information required to perform the action. The title area displays the page title, with the adapter serial number under it - on the Adapter List this is the Hostname. An image relevant to the current page, with the title of the resource, or the resource type under it.
Actions Area
This section contains the actions that can be performed from the current page. That is, the actions that are relevant to the currently selected resource. Disk and Array resource actions are available from the relevant Resource View when accessed through the Logical View.
Some actions result in a form being displayed in the Configuration area, some execute the action immediately, and others provide a JavaScript confirmation window. If JavaScript is not available, the RSM confiramtion page is displayed.Note: Some service actions are only available when the Resource View has been accessed therough the Physical View.
Other Actions:
This action checks whether the level of adapter firmware on your adapter
is the latest. This action requires the machine running the browser to be connected
to the Internet. This action updates the current page This action stops the flashing indicator light on all disks attached to the selected adapter. This action displays the speed at which links capable of 40 Mega-Bytes a second
are actually running. See also Link Speed Health Check.
This action will only be displayed if it was possible to obtain the information
from the adapter. This action starts the Asynchronous Health Check in the adapter. This
health check causes any degraded errors to be logged in the SSA Event Log. This action reads an existing dump file (created with the Dump CFG action) and displays the information on the Configuration Dump page. This action reads the current adapter and resource configuration details and
outputs the information on the Configuration Dump page.
It may take some time to complete this operation in large configurations, and
when the using system is under high load. If your browser times out before the action
completes, increase the timeout value. This action starts the Concurrent Diagnostic funtion on the adapter.
Concurrent diagnostics provide a level of diagnostics that enables the SSA
subsystem to function without a decrease in performance. If the diagnostics
find an error, an event will be raised in the SSA Event Log
and the diagnostics will stop. The error will also be displayed in the
Information Area, below the Navigation Area.
Follow the instructions to resolve the problem, as described under the relevant
SRN information, and resubmit the Diagnostic to ensure no other errors
exist. This action starts the Non-Concurrent Diagnostic function on the
adapter. Non-Concurrent diagnostics run a more detailed level of
diagnostics than the Concurrent version. This means that I/O to the SSA
disk drives must be stopped. You are required to confirm a quiescent system
before continuing with this option. This action switches the current adapter from running as the
Primary Cluster adapter to run as the Secondary
adapter.
All read and write transactions to RAID1 Cluster arrays are directed
through the primary adapter. This should be taken into account
when setting the primary adapter and when balancing the load
between the using systems. This action clears all entries in a stale
Fast Write Cache.
This should only be done when instructed to do so by an
SRN or a service representative. Incorrect usage
may result in loss of important data that may be residing in the cache.
If using the Stand Alone Version, this action requires Config
access. This action resets the battery counter in the Fast Write Cache Feature.
This should only be done when instructed to do so by an SRN or a
service representative. Incorrect usage may result in the battery end of
life not being reported. If using the Stand Alone
Version, this action requires Config access.
