Volume Retention Manager
Normal volumes have the read/write attribute so that you can access and update the data without
any restrictions. By using Volume Retention Manager, you may set the read only attribute, which
prohibit writing operation, or the protect attribute which prohibit both reading and writing
operations. Remember that you cannot create SIz pairs with the volumes with protect attribute.
XP Auto LUN
SIz volumes can be assigned to migration volumes of XP Auto LUN. However, if the SIz S-VOL is
already paired with three T-VOLs, you must delete the SIz pairs before migrating the volumes by
XP Auto LUN. Also, to assign SIz volumes to destination volumes of migration by XP Auto LUN, or
reserve SIz volumes for XP Auto LUN, you must delete the SIz volumes or un-reserve SIz volumes
before using the volumes by XP Auto LUN. If you assign an SIz S-VOL that is already paired with
three T-VOLs to migration volumes of XP Auto LUN, or assign SIz volumes to other XP Auto LUN
volumes than migration volumes, the command will be rejected.
Also, if you split the SIz pair that is assigned to XP Auto LUN's migration volumes, migration of
those volumes will be canceled.
You cannot use migration volumes, destination volumes, and reserved volumes for XP Auto LUN
for SIz pair operations (the command will be rejected). To use XP Auto LUN volumes for SIz pair
operations, you must release the volumes by XP Auto LUN.
HP XP External Storage Software
SIz operations can also be performed in conjunction with XP External Storage operations to create
pairs with external volumes. For the details on the external volumes, see the HP XP24000/XP20000
External Storage Software User's Guide.
Hitachi TrueCopy™ for Mainframe
TCz volumes can be assigned to SIz pairs, and vise versa.
CAUTION: When performing the QuickRestore pairresync operation on the SIz pair which shares
the volume with TrueCopy Asynchronous for Mainframe, SIz S-VOL and T-VOL must be allocated
to the same CLPR. Specify the Reverse Copy mode instead of the Quick Restore mode when
resynchronizing the SIz pair whose S-VOL and T-VOL are allocated to the different CLPR.
HP recommends ShadowImage for Mainframe for intra-storage system copy operations. If
ShadowImage for Mainframe is not installed, TCz (synchronous only) can be used to copy within
the same XP storage system. This TCz configuration requires at least one external Fibre Channel
interface cable loop (a minimum of two is recommended).
ShadowImage for Mainframe and XP Continuous Access for Mainframe can function together in
the same XP storage system to provide both internal and remote backup for your important data.
•
When SIz and TCz pairs share the same volume, to obtain the SIz pair status, query from the
host:
◦ The T-VOL status of the SIz pair if the SIz S-VOL and TCz M-VOL share the same volume,
◦ The T-VOL status of the SIz pair if the SIz S-VOL and TCz R-VOL share the same volume,
and
◦ The S-VOL status of the SIz pair if the SIz T-VOL and TCz M-VOL share the same volume.
•
ShadowImage for Mainframe supports multiple T-VOLs for each S-VOL. If you issue a pair
status query to an SIz S-VOL, the status for only one SIz pair is reported (the pair with the
T-VOL with the lowest LDEV ID). To obtain the pair status for the SIz pairs with the other T-VOLs,
you must direct the host query to the specific T-VOL using the T-VOL’s LDEV ID in the host
