8100 Upgrade Assessment (5697-6985, July 2007)

About this doc ument

The EVA4100/610 0/8 1 00 uses active/active controller failover behavior instead of the active/passive

controller f

ailover behavior in VCS 3.xxx. The change to active/a ctive will impact most host

conﬁgurati

ons. The impact of this change may involve replacing HBAs and drivers, installing new

multi-path

ing software, and re-establishing the correct paths to the storage system LUNs.

upgrading. Any host connected to an EVA4100 /6100/8100 must be conﬁgured to support
