Adding or removing cache or shared memory
When pair status of TC (synchronous/asynchronous/HAM) is COPY, neither cache nor shared
memory can be added to or removed from the storage system. When either of these tasks is to be
performed, first split any pairs in COPY status, then resynchronize when the cache or shared
memory operation is completed.
Enabling XP Continuous Access Options
You must enable the XP Continuous Access option(s) (Asynchronous and/or Synchronous) on the
storage systems using the Remote Web Console software. Each XP Continuous Access option
requires a separate license key code, and each storage system requires its own separate set of
license key codes.
For instructions on using the Remote Web Console software and enabling the XP Continuous Access
option(s), see the HP XP24000/XP20000 Remote Web Console User Guide.
When you use Remote Web Console on UNIX workstations or in other non-Windows environments,
certain additional operating conventions must be followed. For details, see the HP
XP24000/XP20000 Remote Web Console User Guide.
