NOTE:

A journal groups consists

of areas containing journal

data and an area containing

metadata for remote copy.

NOTE:

• Specify a port in SLPR 0 when using LUN Manager to deﬁne an LU path to a data volume. It is

possible, but not recommended, that you specify a port in another SLPR when deﬁning an LU path.

For more information about SLPR 0, see the

HP StorageWorks XP Disk/Cache Partition user guide

• Volumes containing a volume management area (VMA) cannot be used as journal volumes. For

more information about VMA, see the

HP StorageWorks LUN Security XP Extension user guide

Table 11 lists emulation types and capacities of logical volumes that can form pairs. For more information,

see Maximum number of pairs.

Continuous Access XP Journal supports the LUN Expansion (LUSE) feature, which allows you to conﬁgure

a LUSE volume pvol by using 2 to 36 sequential LDEVs. If the pvol and svol of a pair are both LUSE,

the capacity and conﬁgurationofthesecondarydatavolumemustbethesameastheprimarydata

volume. For example, when the primary data volume is a LUSE volume in which 1-GB, 2-GB, 3-GB

volumes are combined in this order, the secondary data volume must be a LUSE volume in which 1-GB,

2-GB, 3-GB volumes are combined in this order. In addition, RAID1, RAID5, and RAID6 can coexist in

the LUSE volume.

Continuous Access XP Journal also supports LUN Volume Manager on the local array, which allows

you to conﬁgure custom-size LUs that are smaller than standard-size LUs. When assigning custom-size

LUs to a Continuous Access XP Journal pair, the secondary data volume must have the same capacity

as the primary data volume.

Table 12 lists the emulation types and capacities of the master and restore journal volumes that can be

used for Continuous Access XP Journal.
