HP XP7 Storage - Manual (Page 80)

•
Cnt Ac-S Z does not allow access to an S-VOL while the pair is split (when mode20=ON,
Read access is accepted).
•
When a pair is split, whether user requested or due to failure, the primary system generates
sense information to notify the hosts. If the host system supports IBM PPRC (and the “PPRC
support by host” CU option is enabled), this notification results in an IEA494I and/or IEA491E
system console message, which indicates the reason for suspension.
