Conﬁguring multipath with the OpenVMS iSCSI Initiator

Multipath support for the OpenVMS iSCSI Initiator is native to OpenVMS. No additional software is

required for full iSCSI multipath support.

When the OpenVMS

Initi ator is loaded, it uses the manual or iSNS discovery mec hanisms to locate all

viable paths to all accessible storage targets. It m aintains an active login with every path to each target.

If the current active path fails, I/O can be automatically failed over to another available path.

As with other interconnects supported by OpenVMS, the multipath software performs initial p ath selection

and is responsi

ble for path failover in the event the active path fails. The user can effect multipath

changes (such as manual path switching) using the DCL command:

SET DEVICE /qualifier /PATH=path-description-string device-name

Path description string format

iSCSI p ath description strings are signiﬁcantly longer than the description strings used for other multipath

interconnects, such as Fibre Channel. An example of a typical iSCSI path description string is shown

in Figure 63 and Table 18.
