PowerPath for UNIX Installation and Administration Guide
PowerPath Administration on Solaris
PowerPath and CLARiiON Storage Systems
PowerPath events or actions that entail LUN trespasses (for example,
SP failovers or
powermt restore commands) can cause the Solaris
disk driver to log warning and/or error messages. You can ignore
these messages, as PowerPath intercepts them and hides them from
the application sending the I/O.
For more information on CLARiiON configuration requirements,
refer to the EMC Installation Roadmap for CX-Series and FC-Series
Storage Systems and the EMC Host Connectivity Guide for Sun Solaris,
available on the Powerlink website.
The Host Connectivity Guide describes how to edit the
/kernel/drv/sd.conf file to suppress ODS device overlap error
messages. Note that this workaround is invalid for Sun Cluster 2.2
configurations.
Ensuring a Sufficient Stack Size
If you install an application that resets the stack size (for example,
VxVM or VxFS) after you install PowerPath, make sure that
lwp_default_stksize and rpcmod:svc_run_stksize are set to at
least 0x6000 on a Solaris 7, 8, or 9 system, and at least 0x4000 on a
Solaris 2.6 system. Other applications may reset the stack sizes to
values insufficient for PowerPath.
Booting a Host With Built-In Fibre Channel Ports
If you boot a Solaris host with all socal host adapters to storage
system volumes disconnected or dysfunctional, PowerPath will not
configure any socal host adapter paths. After physically restoring the
