Managing Power for Storage Systems and Network Relay
Devices
This sect
ion explains power managem ent for storage systems and network relay devices during remote
copy oper
ations. In particular, this section discusses the following:
• What happens when power is removed from storage systems or network relay devices due to an
unexpected reason (see “When the Power Stops Unexpectedly” on page 106)
• What sho
uld
be noted when you power off storage systems or network relay devices intentionally
(see “T
urning the Power Off Intentionally” on page 1 07)
Here, t
he
term network relay device refers to the hardware used for connecting the primary and
secondary storage systems, such as ESCON directors, channel extenders, and switches.
When the Power Stops Unexpectedly
This section explains what happens when power is removed from storage systems or network relay
devices due to an unexpected reason.
When the Power is Removed from the Primary Storage System
If power is removed from the primary storage system during remote copy operations, the primary storage
system assumes that a failure occurred, and then splits all data volume pairs. If the primary storage
system splits data volume pairs, the secondar y storage system also assumes that a failure occurred,
and t
hen
splits all data volume pairs.
If power is removed from the primary or secondary storage system and its backup batteries are fully
discharged while data volume p airs are split, differential data (that is, update data) will not b e retained.
In
this unlikely case, the p rimary or secondar y storage system assumes all the suspended data volumes
are updated. If you restore the data volume pairs at the primary site, all the primary data volumes
wil
l
becopiedtothe secondary datavolumes.
When the Power is Removed from the Secondary Storage System
If power is removed from the secondary storage system during remote co py operations, the secondary
storage system assumes that a failure occurred, and then splits all data volume pa irs. If the secondary
storage system splits data volume pairs, the primary storage system also assumes that a failure occurred,
and then splits all data volume pairs.
