TC390 operations involve the main (primary) disk arrays and the remote (secondary) disk arrays. This
chapter covers TC390 operations in which the main disk array is an XP12000/XP10000 and the remote
disk array is an XP12000/XP10000 or other XP disk array. The main disk arrays contain the TC390 main
volumes (M-VOLs), which contain the original data and are online to the host(s). The remote disk arrays
contain the TC390 secondary volumes (R-VOLs), which are the synchronous or asynchronous copies of the
M-VOLs. TC390 supports all CU images and logical volumes of the XP12000/XP10000. TC390 supports
RAID1, RAID5, and RAID6 configurations (see Table 2 .)
All XP12000/XP10000 with TC390 installed are compatible with the IBM PPRC host software function. For
more information on PPRC, see ” Using PPRC commands for TrueCopy ” on page 157. TC390 also supports
all physical hard disk drive options and RAID1, RAID5 and RAID 6 configurations for the
XP12000/XP10000.
To provide greater flexibility and to enable the XP12000/XP10000 to be tailored to unique customer
operating requirements, additional operational parameters, or optional modes, are available for the
XP12000/XP10000. At installation, the XP12000/XP10000 modes are set to their default values so HP
recommends that you discuss these settings with your HP representative. Only your HP representative can
change the XP12000/XP10000 modes. Table 3 shows the XP12000/XP10000 modes related to TCz and
PPRC operations.
