Suspend - HP StorageWorks XP24000 User Manual

Write requests at the S-VOL will start when all QUIESCE conditions are released. The following
conditions cause the XP storage system to automatically release the QUIESCE condition:
A CSUSPEND TSO command without the QUIESCE parameter is accepted.
A CDELPAIR TSO command is accepted.
A Delete, Suspend, or Split Pair command (from the Remote Web Console computer) is
accepted.
Storage system power-on-reset is executed.
If a ShadowImage for Mainframe pair is suspended because of an internal storage system error
condition, the QUIESCE option is applied. In this case, release the QUIESCE condition by deleting
the pair.
SIz and TCz are processed independently. The CSUSPEND/QUIESCE command is effective for
either the SIz or TCz pair specified in the command.

DDNAME = dname = JCL statement identifying
the volume.
SYSNAME = sysxxx = SYSNAME in the
ASSGN system control statement.
UNITADDRESS = ccuu = device number.
Primary volume (S-VOL): SSID, serial number,
and channel connection address.
You can set MPS00 or MAnn0 instead of a
serial number where nn is the CTG ID.
Secondary volume (T-VOL): SSID, serial
number, and channel connection address.

Description
You should specify only one parameter of the
three parameters. The italic part on the left
means that it is the arbitrary name. For
example, dname means the arbitrary unique
name of the JCL statement which identifies the
volume.
The parameter MPS00 is for a steady split
request.
The parameter MAnn0 is for a quick split
request on all pairs in a CTG.
If you set a parameter other than the serial
number, MPS00 or MAnn0 will be rejected.
SIz does not use this parameter. SIz ignores it.
