Appendix B Brocade Communications Systems Switch Troubleshooting 87
QuickLoop
QuickLoop is a feature of the Brocade Silkworm switches that allows hosts with host
bus adapters (HBAs) that are not fully Fabric-aware to communicate with other
devices attached to the switch. In addition, QuickLoop allows switches to replace
hubs in a private loop environment. QuickLoop is a separately licensed product.
Note –
For the Brocade Sun StorEdge SAN 4.0 Release phase, Sun StorEdge T3 and
T3+ arrays do not need Quickloop, nor do host bus adapters. Sun StorEdge T3 and
T3+ arrays will auto-configure as L_Ports and HBAs will auto-configure as F_Ports if
the switch is in the fabric mode.
Current Issues with the Storage Automated
Diagnostic Environment Version 2.1 and Brocade
Switches
The minimum Brocade Silkworm switch firmware to use with Storage Automated
Diagnostic Environment version 2.1 is v2.6.0c.
Diagnostic Tools
The tools available for troubleshooting differ from the original release of the Sun
StorEdge SAN 4.0 Release. Since then, Sun StorEdge StorTools 4.x and Network
Storage Agent 2.1 have had their functionality combined into a single diagnostic
package called the Storage Automated Diagnostic Environment version 2.1. Brocade
Silkworm switches also have their own GUI called WebTools.
Storage Automated Diagnostic Environment
Version 2.1 and Brocade Switches
With the Storage Automated Diagnostic Environment version 2.1, Brocade switches
are now supported under the same diagnostic framework as the rest of the Sun SAN
product family. This support includes monitoring for error and alert conditions,
revision checking, graphic topology display, and fault isolation diagnostics.
