Causes:A failure occurs to the application for
monitoring the volumes installed in a host.
• Free space of the pool is insufficient.

Causes:When you are operating Remote Web
Console, a timeout occurs frequently.
• The load on the Remote Web Console computer is too heavy, so that
it cannot respond to the SVP.
• The period of time until when time-out occurs is set too short.
Solutions:
• Wait for a while, then try the operation again.
• Verify the setting of the environment parameter of Remote Web
Console RMI time-out period. For information about how to set the
RMI time-out period, see the HP XP7 Remote Web Console User
Guide.
Solutions:THP V-VOL capacity cannot be increased.
• After refreshing the display, confirm whether the processing for
increasing THP V-VOL capacity meets conditions described in
“Requirements for increasing THP V-VOL capacity” (page 57).
• Retry the operation after 10 minutes or so.
