Note on Behavior of Alternate Path when EVA Storage System is Connected

When an EVA storage system is connected, the behavior of the alternate path

differs depending on the microprogram version of the EVA storage system.

If the storage system type is EVA3000/5000, the behavior of the alternate

path differs between the EVA storage systems of the microprogram version

4.000 or later and the EVA storage systems of the earlier microprogram

versions.

If you want to replace the microprogram of the EVA storage system, check

whether the behavior of the alternate path changes as a result of changing the

microprogram version. If the behavior of the alternate path changes, perform

the Delete Volume operation of Universal Volume Manager to release the

setting of mapping the EVA storage system volume before you actually replace

the microprogram.

Refer to the EVA storage system documentation for how the behavior of the

alternate path changes.

System Parameter Settings for Connecting Sun StorEdge 6120/6320

When you connect a Sun StorEdge 6120/6320 as an external storage system,

set the system parameters of the Sun StorEdge 6120/6320 according to the

following table. For the system parameters that are not in the following table,

refer to the documentation of the Sun StorEdge 6120/6320 and set the

parameters appropriately for the connecting configuration.
