TrueCopy for Mainframe: If the status of a TrueCopy for Mainframe volume is suspended or

simplex, the volume can be used as a source volume. If not, the volume cannot be used as a

source volume. When a TrueCopy for Mainframe volume is deleted from the MCU, the status of

both volumes changes to simplex, and both volumes can be used as source volumes. When a

TrueCopy for Mainframe volume is deleted from the RCU, the status of the M-VOL changes to

suspended and the status of the R-VOL changes to simplex, and both volumes can be used as

source volumes. Note that if you specify a TrueCopy for Mainframe volume as a source volume,

you cannot specify an external volume as the target volume.

HP StorageWorks XP Continuous Access Software: If the status of a Continuous Access volume is

PSUS,PSUE, or SMPL,the volume canbeusedasasource volume. Ifnot,the volume cannot be

used as a source volume. When a Continuous Access pair is deleted from the MCU, the status

of both volumes changes to SMPL, and both volumes can be used as source volumes. When a

Continuous Access pair is deleted from the RCU, the status of the P-VOL changes to PSUS and the

status of the S-VOL changes to SMPL, and both volumes can be used as source volumes. Note

that if you specify a Continuous Access volume as a source volume, you cannot specify an

external volume as the target volume.

Universal Replicator for Mainframe: If the status of a Universal Replicator for Mainframe volume

is PendingduplexorDuplex, thevolumecannotbeusedasasource volume. Notethatifyou

specify a Universal Replicator for Mainframe volume as a source volume, you cannot specify an

external volume as the target volume.

Continuous Access Journal: If the status of a Continuous Access Journal volume is COPY or PAIR,

thevolumecannotbeusedasasource volume. Notethat ifyou specifya Continuous Access

Journal volume as a source volume, you cannot specify an external volume as the target volume.

ShadowImage for Mainframe and HP StorageWorks XP Business Copy Software: Usage of

ShadowImage for Mainframe and Business Copy volumes as a source volume depends on the

status and cascade conﬁguration of the volume as described below.

• The following volumes cannot be used as a source volume:

• ShadowImage for Mainframe volumes whose status is SP-Pend or V-Split.

• Business Copy volumes whose status is COPY(SP) or PSUS(SP).

• Table 2 on page 17 speciﬁes which non-cascade volumes can be used as source volumes.
