CAUTION:

Persistent EVA overload may indicate an overloaded conﬁguration and additional array host port

resources may be required to match the conﬁguration to the actual workload. Consult your local HP

account or service representative for help to properly conﬁgure the EVA for your newly designed or

existing conﬁguration.

High-availability environment recommendations

In high-availability environments, under heavy I/O loads, you may experience I/O time-out conditions. If

I/O timeouts occur, HP recommends that you use the pvchange com m and to increase the IO_tim eout

value from the default value of 30 seconds to no m ore than 60 seconds. Under heavy I/O load

conditions, the increased IO_timeout value allows for longer I/O completion times and for LUN access

delays if a controller failover condition occurs.

NOTE:

Ensure that you have HP MC/ServiceGuard conﬁguredproperly.Fordetails,gotothefollowingwebsite:
