HP StorageWorks XP Remote Web Console Software - Manual (Page 96)

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.
Figure 42 (page 96) shows an example of the CSUSPEND command.

CSUSPEND DEVN (X ‘DE80’ ) PRIM (X ‘0080’ ,30158,X ‘00’ ) SEC (X ‘0080’ ,30158,X ‘01’ )
SUSPEND
Table 40 (page 96) lists and describes the SUSPEND command parameters that can be used when
you split SIz pairs.
Table 40 SUSPEND Command Parameters
Description Value Parameter
You should specify only one parameter of the
three parameters. The italic part on the left DDNAME = dname = JCL statement identifying
the volume. DDNAME,
SYSNAME, or
UNITADDRESS
means that it is the arbitrary name. For
SYSNAME = sysxxx = SYSNAME in the
ASSGN system control statement.
example, dname means the arbitrary unique
name of the JCL statement which identifies the
volume.
UNITADDRESS = ccuu = device number.
The parameter MPS00 is for a steady split
request. Primary volume (S-VOL): SSID, serial number,
and channel connection address. PRI
The parameter MAnn0 is for a quick split
request on all pairs in a CTG.
1
You can set MPS00 or MAnn0 instead of a
serial number where nn is the CTG ID.
If you set a parameter other than the serial
number, MPS00 or MAnn0 will be rejected.
Secondary volume (T-VOL): SSID, serial
number, and channel connection address. SEC
SIz does not use this parameter. SIz ignores it. Not applicable. PRIMA

1 If you perform a quick split request on all pairs in a CTG, confirm that the status of all pairs in the group is DUPLEX. If
there are one more pairs whose statuses are PENDING in the group, the quick split operation sometimes ends abnormally
(CC = 12). If this occurs, wait until the copy operation for that pair ends.
2
The parameter is valid only for the DKC emulation type 3390. If the DKC emulation type is 2105 or 2107, the TSO
command ignores the parameter and the ICKDSF job ends abnormally (CC = 12).
3 The CSUSPEND QUIESCE option has been disabled by APAR OW15247 or APAR OW15248. See either of these
APARs and the latest IBM PPRC documentation for detailed information about the QUIESCE option. Check with your HP
