Albert Reply to: 2003-07-25 16:22:35 Talk about my experience to SAN. In addition to some of the more basic, such as ZONING, SAN actually has some more complex SAN software technology, such as ISL TRUNKING, Secure Fabric OS, Fabric Watch (Brocade), etc. However, I want a SAN switch to connect, how to ensure that it is normal to run. I think many people may think San Switch may not be so friendly, and I don't know if they are doing. In fact, the soul of the SAN switch is its OS, but their OS is simple, unlike Unix is so huge, the OS like the Brocade 2xxx is VxWorks, Brocade 3xxx, 12000 is improved, use Linux kernel. And UNIX is not much longer than the SAN switch OS, the command parameter is almost not much. So the management operation of the Fabric OS should not be a problem. But my headache is that many of the results returned by the order seems to be very complicated. At first glance, I don't understand, and I don't know if I have used it. Now there are some system management software, such as HP OpenView, IBM Tivoli, CA TNG Unicenter, etc. These software can be integrated with SAN management? The answer is affirmative, I summarized the method (2): 1. Download MIB for your San Switch There are two regulatory methods here, one is active, one is passive. What is active, that is, when the switch changes in their own state, actively send SNMP TRAP to Management Server, you only need to set SNMP Trap RecePient to your Management Server on the SAN switch, and the Communication String To set it, Then do the corresponding filter settings on your Management Server, you can receive the Message you care when there is change in the switch status. What is passive, that is, the MIB value on the Poll SAN switch (these MIB values are derived from the Downloaded MIB library) and set the appropriate threshold on the Management Server, then when the threshold is detected, Message can be generated in a suitable warning level. 2. Fabric Watch (Brocade's Product) Sets the appropriate threshold in the Fabric Watch. When the threshold exceeds, the generated Message can be sent to your Management Server in the way SNMP TRAP, or you can send it to a Unix server Syslog inside. Then actually you can use some way (such as the log file encapsulator in HP VPO) to filter the Message in syslog, and then get the Message you care about on Management Server. This way you can learn about the dynamics of the SAN switch, you can look forward to some bad trends, take steps to ensure the safe operation of SAN. Maybe my expression is a bit misleading, MIB is not a software, MIB (Management Information Base), actually it is a collection of management information.
Each MIB Object represents a status or configuration information of managed nodes (such as a SAN Switch).
For example, the simplest configuration information Switch name, it is a MIB Object, each MIB Object has a corresponding value, and these values are not stored in a fixed database, but your Management Server (Tivoli)
Send a request to the SNMP Agent on Managed Node periodically, then by Managed Node
The SNMP Agent acquired this MIB Object in this Managed Node by calling a corresponding applet.
Of course, you can also set this MIB Object on the command of the SNMP SET on the command of the SNMP SET.
Value.
How do you know how to get those values? This is the role of the MIB library, with a MIB library, and Management Server knows which MIB Object values to go. The name of these MIB Object is the name of these MIB Object. These MIB Object organizes a tree structure (see Tivoli Information for the introduction of MIB), MIB library is provided by EMENGEMENT Software (OpenView, Tivoli) The MIB library of many common devices has been installed default, but some new devices such as Brocade Switch, you need yourself to Download to your Management Software on your BROCADE website.
I haven't used Tivoli, but I want to be similar to OpenView, and there is MIB Browser and Load Mib menu options in OpenView NM.
You can access http://www.brocadeconnectapac.com to get the MIB library you want
(In Tools & Utilities-> MIBS & RSH Utilities).
However, you must use your San Switch WWN to access this URL.
