EMC PowerPath & SRDF problem: How to change FC timeout

Hi there

When using EMC PowerPath and a couple of EMC Symmetrix in synchronous
SRDF mode, I encounter a regular loss of PowerPath channels to my HP 9000.
If in SRDF adaptive copy mode, ther are no problems at all.

Is it possible to extend timeout periods on A3404 / A5158A FC (FCP) drivers ?

Thanks for any help

Cheers

Orlando

You can extend timeout value for each physical volume with pvchange command.
Please refer to man page, pvchange(1m).

# pvchange -t
