Managing multipathing

VMware deﬁnes the path states as:

• Active—The path is working and currently used for all data transfers.

• Disa

bled—The path is disabled and no data can be transferred.

• Standby—The path i s working but not currently used for transferring data.

• Dead—The initiator cannot connect to the storage via this path.

VMware LUN multipathing policies

Multipathing policies supported by VMware include:

• Fixed—The ESX server always uses the preferred path when that path is available. If it cannot

access the LUN through the preferred path, then it fails over to alternate pa th. Fixed is the default

policy for Active/Active arrays. Fixed is the default policy.
