IBM Director can manage up to 5,000 clients depending on configuration density. Powerful remote management functions...
IBM Director recognizes two types of managed systems: native agents (IBM Director Agent installed) and nonnative agents (SNMP agent installed). The Agent comes preinstalled on all IBM NAS appliances. It runs as a service that is automatically started at boot time. IBM Director Agent provides valuable information to IBM Director management server and other supported management applications.
1. Although you can do so, it is recommended that you not change the default computer name to avoid the chance of propagating misidentification through the system. And, if you are using IBM Director to manage your appliance, and you change the default name, the default name continues to appear in IBM Director.
This includes upgrading the IBM Director client itself. The basic delivery is a single file package that is signed with a unique IBM NAS key. Only IBM can create the signed packages that can be used by the IBM Director Software Distribution tool.
IBM Director clients receive any given package. By default, software distribution packages automatically install themselves immediately following delivery to the IBM client. Delivery of the package can be done manually or scheduled for a later, more convenient time.
NAS groups to the IBM Director Server and Consoles by downloading the InstallShield extension from the IBM Web site and invoking the executable file. This will create a new Group on all consoles that represent IBM NAS appliances in the managed network.
The eSA agent must be installed on all IBM NAS appliances that you want to participate in this service. You can download the software from the following URL: www.pc.ibm.com/qtechinfo/MIGR-4L4QVC.html Predictive Failure Analysis Predictive Failure Analysis (PFA) provides advanced notification of a pending failure so that corrective action can be taken to avoid unplanned downtime.

Appendix E. Setup procedures and diagnostics for the Fibre Channel Hub This appendix provides setup and diagnostic information for the IBM 3534 Fibre Channel Hub, Model 1RU. Note: Throughout this section, the term switch refers to switches and hubs unless otherwise noted.
1. Connect a serial cable that shipped with the hub (not null-modem) between the serial port on the hub and COM1 of the system 2. Open a HyperTerminal Session from the managing system. 3. Choose a name for the session. 4.
Attaching to the serial port while the hub is on 1. If the hub is on, you can attach your service terminal, login, and run most diagnostics. However, you need to get an administrator username and password recognized by the hub from the system administrator. 2.
POST runs differently depending on the startup method. A power cycle (disconnecting from power and reconnecting to power) is considered a cold start. All other starts from a powered-on state (such as restart or panic) are considered warm starts. From a cold start condition, executing a POST runs the long version of ramTest. From a warm start condition, executing a POST runs a shorter version of ramTest.
Diagnostic command descriptions camTest Verifies that the SID translation required by QuickLoop and implemented using content addressable memories (CAM) are functioning correctly. centralMemoryTest Checks the central memory in each ASIC as follows: v Built-in self-repair (BISR) circuit in each ASIC chip does not report failure to repair bad cells (bisr test).
This command behaves differently according to the modes activated as follows: switchEnable or switchDisable mode v Online mode In the online mode, where the hub is enabled prior to executing the test, the test only tests ports that are cable-loopbacked to ports in the same hub.
50-55 seconds for warm or cold starts. A hub restarted without POST generates the DIAG- POST_SKIPPED error. Note: IBM recommends that POST processing always be executed to ensure the operational status of the hub during the start up stage.
executes diagShow every 4 seconds, continuously, until stopped by pressing Enter. This may be used to isolate a bad GBIC. A port with a changing LLI_errs value is prefixed by ** in the display. portLoopbackTest Verifies the intended functional operation of the hub by sending frames from each port’s transmitter back to the same port’s receiver through an internal hardware loopback.
The state of the GBIC mode is saved in flash and stays activated (even after restarts or power on and off cycles) until it is disabled as follows: sw:admin> setGbicMode 0 An example mode of operation is to disable the hub, set the GBIC mode to 1, and execute the spinSilk command which would limit its testing to: v All ports with GBIC and embedded optics present.
The command is entered with the following parameters: v firstPort specifies the first port of range of ports to dump information. The default, if no operand is specified, is to print the state of port 0. If only firstPort is specified, only the information for firstPort is printed.
