HP StorageWorks XP Remote Web Console Software - Manual (Page 28)

The following conditions cause the storage system to output the ADR935W message, and end with
CC = 4 (copy operation is performed via the host):
•
The size of the T-VOL is larger than the S-VOL within the same CU image.
•
The emulation types of the S-VOLs and T-VOLs are different within the same CU image.
When the SSID boundary is 64 LDEV and you establish a relationship between two volumes that
have the same CU image but different SSIDs, copy data from S-VOL to T-VOL using the host program.
Releasing a Version 1 Relationship Using FCWITHDR
Use the FCWITHDR command of PPRC TSO to release a Version 1 relationship. The specified
volume must have an established relationship.
When the SSID boundary is 64-LDEV, the S-VOL and the T-VOL for Version 1 must be established
in the same CU image and SSID. When the S-VOL and the T-VOL are in different CUs or different
SSIDs, delete the relationship from the ShadowImage for Mainframe Pair Operation window.
(page 28) lists the parameters you can use with the FCWITHDR command.
Table 18 Parameters for the FCWITHDR Command (Version 1)
Description Value Parameter
Specify the number (device address) of
the S-VOL on which you want to
perform the FCWITHDR command. Source device number. SDEVN
Specify the number (device address) of
the T-VOL on which you want to
perform the FCWITHDR command. Target device number. TDEVN
(page 28) shows an example of the FCWITHDR command.
Figure 11 FCWITHDR Command
FCWITHDR SDEVN(X'DE80') TDEVN(X'DE81')
CAUTION: If a relationship is deleted by the FCWITHDR command, the data integrity of the
T-VOL cannot be guaranteed.
Version 1 does not support the REMOVEFCPY parameter of the ICKDSF CONTROL command. To
delete all of the Version 1 relationships established in the storage system, you need to perform this
operation using the ShadowImage for Mainframe Pair Operation window.
Viewing the Relationship Status of Version 1 Using FCQUERY
Use the FCQUERY command of PPRC TSO to release a Version 1 relationship. (page 28) lists the
parameter you can use with the FCQUERY command.
Table 19 Parameter for the FCQUERY Command
Description Value Parameter
Specify the number (device address) of
the volume whose status you want to
check. Device number DEVN
(page 29) shows an example of the FCQUERY command.
