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 XP1024/XP128/XP12000/XP10000
and the remote disk array is either an XP1024/XP128/XP12000/XP10000 or other XP disk arrays. 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 XP1024/XP128/XP12000/XP10000. TC390 supports RAID1, RAID5, and RAID6 configurations (see
Table 3.
All XP1024/XP128/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 153. TC390 also supports all physical hard disk drive options and RAID5/RAID1 configurations for
the XP1024/XP128/XP12000/XP10000.
To provide greater flexibility and to enable the XP1024/XP128/XP12000/XP10000 to be tailored to
unique customer operating requirements, additional operational parameters, or optional modes, are
available for the XP1024/XP128/XP12000/XP10000. At installation, the
XP1024/XP128/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
XP1024/XP128/XP12000/XP10000 modes. Table 4 shows the XP1024/XP128/XP12000/XP10000
modes related to TCz and PPRC operations.
