HP StorageWorks 2/32 SAN switch 2/32 version 4.0.2b release notes - Page 10

HP Recommendations HP Recommendations HP always recommends redundant fabrics and multi-pathing software for uptime-sensitive environments. Examples of scenarios protected by redundant fabrics include, but are not limited to: ■ Add / Move / Change operations for devices or switches ■ Changing the core PID format ■ Changing any other fabric-wide parameters (for example, ED_TOV) ■ Erroneous zoning changes / user error ■ Major upgrades / changes to fabric architecture ■ Physical disasters, for example, water pipe breaks above "fabric A" rack HP recommends strongly against using drivers that bind by PID. There are several routine maintenance procedures which may result in a device receiving a new PID; the core PID format update is just one example of such a procedure. Examples include, but are not limited to: ■ Changing "Compatibility Mode" settings ■ Changing switch domain IDs ■ Merging fabrics ■ Relocating devices to new ports or new switches (that is, for Add, Move, Change type operations) ■ Updating the core PID format ■ Using hot spare switch ports to deal with failures Firmware Overview Firmware v4.0.2b works with HP StorageWorks 2 Gbps switch models only. The firmware will not work if loaded onto HP StorageWorks 1 Gbps switch models. HP recommends that all switches supported by the 4.0.x code stream be updated to Version 4.0.2b together, so all supported switches operate with the same version code. Firmware Version 4.0.2b contains the fully supported Web Tools Graphical User Interface (GUI). Instructions for downloading the firmware are contained on the Software CD. 10 SAN switch 2/32 Version 4.0.2b Release Notes
