HP StorageWorks XP Remote Web Console Software - Manual (Page 19)

CAUTION: The following restrictions apply if CC will be used with Compatible PAV:
•
Ensure that the emulation type of all LCUs is either 2105 or 2107. Only 2107 controller
emulation is available when you use Compatible Hyper PAV. For CC, 2105 or 2107 emulation
cannot be intermixed with other emulation types within the same subsystem.
•
If CC volumes already exist, you must change to 2105 or 2107 emulation as follows:
1.
Stop all Concurrent Copy jobs.
2. Change the DKC emulation type of all CHA packages in the storage system to 2105 or
2107.
3. Restart Concurrent Copy jobs.
Preparing the Storage System for Compatible PAV Operations
Configuring your Remote Web Console Computer
To perform Compatible PAV operations, a WWW client computer must be connected via a LAN
(local area network) to the storage system. The WWW client computer requires a Remote Web
Console program downloaded to the computer. The WWW client computer also requires
appropriate browser settings. For more detailed instructions, see the HP StorageWorks
XP24000/XP20000 Remote Web Console User’s Guide.
Changing the Controller Emulation Type
For Compatible PAV operations the storage system must have channel adapter (CHA) packages
for which the 2105 or 2107 emulation type is specified. If you use Compatible Hyper PAV, only
2107 emulation type is available. Ask your HP representative to verify that the correct CHA
packages are installed.
The HP representative can check and change the controller emulation type in any one of the
following ways:
•
Add CHA packages, and set the emulation type of these packages to 2105 (I-2105) or 2107
(I-2107).
•
Use the System Tuning function on the SVP to change the emulation type to 2105 or 2107,
and power off and then power on the storage system.
CAUTION: For CC, the 2105 or 2107 emulation type cannot be intermixed with other emulation
types within the same subsystem. If your storage system is already performing CC operations, see
Table 3 (page 17) for instructions on implementing Compatible PAV with these functions on the
same subsystem.
Enabling the Compatible PAV Option
You must set the controller emulation to 2105 or 2107 (see “Changing the Controller Emulation
Type” (page 19) before you can enable the Compatible PAV options (only 2107 is available if
you use Compatible Hyper PAV). You need to enable Compatible PAV option to perform Compatible
PAV operations. To use Compatible Hyper PAV, you need to enable both the Compatible PAV
and Compatible Hyper PAV program options.
To enable the Compatible PAV options:
