Last updated on JULY 29, 2016

Applies to:

Solaris Operating System - Version 10 11/06 U3 and later
Oracle Solaris on x86-64 (64-bit)
Oracle Solaris on SPARC (64-bit)
This document only relates to zpools/ZFS in combination with EMC PowerPath LUNs

Symptoms

Cannot create (or import) a ZFS pool on the passive path for an EMC PowerPath LUN.
zpool create fails with internal error: Invalid argument

Active-passive means that only one interface to a device is active at a time,
and any others are passive with respect to that device and waiting to take over if needed. In an active-passive storage system,
if there are multiple interfaces to a logical device, one of them is designated as the primary route to the device.

 For example:

60 is for SPA(Port 0) and 68 is for SPB(Port0). c8t5006016041E004C7d15 device
is being accessed through the ACTIVE path.  c8t5006016841E004C7d15 device is   being accessed through the PASSIVE path.
