Shadowimage For Mainframe Software Requirements; License Requirements - HP StorageWorks XP24000 User Manual

Emulation type
Only volumes with mainframe emulation type such as 3390-3, 3390-3A, 6588- 1 can be
used.
You need to select the volumes of the same emulation type for S-VOL and T-VOL. However,
as for the DKC emulation types, there is no restriction. The DKC emulation type for the S-VOL
and T-VOL can be the same or different (for example, 3990 S-VOL and 2105 T-VOL).
Logical DKC (LDKC), CU, LDEV number
You can use volumes whose LDKC:CU:LDEV (a combination of an LDKC number, a CU number,
and an LDEV number) is within the range of 00:00:00 to 00:FE:FF, or 01:00:00 to 01:FE:FF.
Number of T-VOLs per one S-VOL
You can assign up to three T-VOLs to one S-VOL. However, you cannot assign two or more
S-VOLs to one T-VOL.
Maximum number of pairs
Up to 16,384 SIz pairs can be created (when S-VOLs and T-VOLs are in a one-to-one
relationship).
Even if the above requirements are fulfilled, the URz journal volumes cannot be used for creating
SIz pair.

ShadowImage for Mainframe Software Requirements

To use ShadowImage for Mainframe, all XP hardware, microcode, and software required for SIz
operations must be installed and enabled. You also need to purchase the license key of
ShadowImage for Mainframe and install it in Remote Web Console. For detailed information about
the license key and software installation, see the HP StorageWorks XP24000/XP20000 Remote
Web Console User's Guide.
Operate the Remote Web Console computer in modify mode to perform SIz operations. Users in
view mode can only view SIz information, but they cannot create new pairs or change the pair
status. For information about how to set up and use the Remote Web Console computer, see the
HP StorageWorks XP24000/XP20000 Remote Web Console User's Guide.

License Requirements

SIz license capacity will be required for SIz S-VOLs, T-VOLs, and reserved volumes. You need to
make sure that the SIz license capacity will be larger than the total capacity of these volumes when
you decide the SIz license capacity.
Even if a volume is used for multiple purposes, only the capacity of this volume itself is added to
the total volume capacity. There is no need to multiply the capacity of this volume by the number
of purposes it is used for. For example, if you specify a volume as an S-VOL, and use it as a
reserved volume as well by setting its reserve attribute, only the capacity of the volume itself is
added to the total volume capacity and there is no need for it to be doubled.
The following illustrations are case examples showing how to calculate the total capacity of volumes
that you will use with ShadowImage for Mainframe. For these examples, the capacity of each
volume is assumed to be 1. The colored volume or volumes represent the volumes that are used.
