I/O Load Balancing and Multi-Pathing Policies

The estape driver uses path_lockdown

method as load balancing policy and has minimal support for

multi-pathing.

When the device is ﬁrst opened after a system boot, a path is chosen and will remain ﬁxed. If the path

fails, the new path will be picked on next open only. But with the support of the

lpt_to_lockdown

attribute beginning in the HP-UX 11i v3 March 2009 Update, it lets users select a lunpath among avail-

able lunpaths to the device, which will be locked down and I/O’s will be issued on the newly selected lun-

path.

Refer to the

scsimgr attribute table in scsimgr(1M) for more information on the lpt_to_lockdown

attribute.
