Failure Condition
Activated if the
FREEZE option is
enabled for the
affected LCU pairs. (1) The RCU reports
IEA480 message (SIM
for LDEV blocked) to
either the MCU or the
host processor
(whichever issues the
next I/O first) when
the next I/O is issued
to any volume in the
parity group. If MCU
receives the SIM, it
passes the SIM to the
attached host
processor, and the
IEA480 message is
reported when the
next I/O to this MCU
is issued to any main
volume paired with the
volume in the parity
group.
(2) One (or more)
IEA494 messages
showing EXTENDED
LONG BUSY are
displayed.
(3) One (or more)
IEA491 and IEA494
messages showing
PAIR SUSPENDED are
displayed.
Yes Failure of two physical
devices in a parity
group
Not activated (1) The RCU reports
IEA480 message (SIM
for cache blocked) to
either the MCU or the
host processor
(whichever issues the
next I/O first). If MCU
receives the SIM, it
passes the SIM to the
attached host
processor. Therefore,
IEA480 is reported
when the next I/O to
any device in this
MCU issued.
(2) No IEA491 or
IEA494 messages are
displayed.
