TC390 supports concurrent operations with the following data management functions:
•
Virtual LVI/LUN. Virtual LVI/LUN volumes can be assigned to TC390 pairs as long as the R-VOL has the
same or larger capacity than the M-VOL. If you need to perform Virtual LVI/LUN operations on an
existing TC390 M-VOL or R-VOL, you must delete the pair first to return the volume to simplex status. For
further information on Virtual LVI/LUN, see the HP StorageWorks XP LUN Configuration and Security
Manager user guide for your disk array model.
•
Cache LUN XP. Cache LUN XP volumes can be assigned to TC390 pairs and Cache LUN XP operations
can be performed on TC390 M-VOLs and R-VOLs.
•
SANtinel - S/390. SANtinel operations do not affect TC390 operations. Secure volumes can be
assigned to TC390 pairs, and TC390 volumes can be assigned to secure ports and/or groups for
SANtinel operations.
NOTE:
TC390 R-VOLs cannot be accessed by any host except when the pair is split.
•
HXRC. The XP12000/XP10000 is functionally compatible with the IBM Extended Remote Copy (XRC)
function. See
•
SI390. SI390 volumes can be assigned to TC390 pairs and TC390 volumes can be assigned to SI390
pairs. For information on TC390 and SI390 shared volume configurations, see ”
with other data management operations
” on page 57. This configuration requires at least one external
ESCON or fibre cable loop.
NOTE:
When TC390 and SI390 are both active on the same XP12000/XP10000, TC390 cannot
be used to copy within that disk array. SI390 is recommended for disk array-internal copy. If SI390
is not active, TC390 Synchronous supports intra-disk array copy and requires at least one external
cable loop.
•
Prioritized Port Control. The initiator ports in the MCU do not support the Prioritized Port/WWN
Control option because they are dedicated for TC390 operations.

NOTE:
When TC390A, XP Continuous Access and Hitachi Universal Replicator coexist in the same
XP12000/XP10000 disk array, TC390A pairs, XP Continuous Access pairs and Hitachi Universal Replicator
pairs cannot be mixed in one consistency group. If an XP Continuous Access pair is allocated to Consistency
group No. 00, the TC390A pair and Hitachi Universal Replicator pair cannot be allocated to Consistency
group No. 00. TC390A and XP Continuous Access share the same cache sidefile area.
