Fabric Watch Monitoring in a DRM Environment - Application Notes

Notable Events to Monitor with DRM
Application Notes – Fabric Watch Monitoring in a DRM Environment 29
Managing MIBs
Compaq Insight Manager XE is used to perform the most common SNMP functions. These functions
include:
• Registration of new Compaq and third-party MIBs
• Modification of registered MIBs and related browsing of all MIB variables
• Deletion of obsolete or unused MIBs
• Uploading new MIBs to be registered
• Use of trap categories for organization and event queries
To obtain MIB files for your switch:
1. Go to http://www.compaq.com/storage/siteindex.html.
2. Under Interconnect Products, click the desired Fibre Channel switch.
3. Click Software & Drivers.
4. Click the desired MIB files to download.
Notable Events to Monitor with DRM
In a DRM environment, it is very important to monitor for those events that identify problems with
critical components going down, dropping out, being compromised, or becoming over taxed. The
following are items you may want to monitor in a DRM environment:
• Checking for intermittent (or unstable) long-distance links
• Monitoring critical E_Ports
• Monitoring security changes to the fabric
• Monitoring traffic load balances
In describing how to configure these items below, only the Web Tools method is discussed. Telnet and
the use of a configuration file are also valid methods used to set up monitoring for these items.
Checking for Intermittent (or Unstable) Long-Distance Links
You should know the characteristics of your fabric and what conditions can be expected or tolerated
during normal operation. Direct fiber connections should be very stable and something you would not
expect to become unstable. Long-distance links are critical to allowing replication between separated
sites. At a minimum, two areas in the E_Port class should be monitored to warn you of intermittent
conditions with long-distance lines. State changes should be monitored for every E_Port connecting to
long-distance lines, and each of these E_Ports should be monitored for link loss. Refer to Figure 17 for
a view of the settings to select and Table 5 for a description of the settings on the screen.
