6 DESCRIPTION: In Windows, reports are
not displayed when the HTML button is
clicked in the Storage Utilization by Host -
Reports subwindow or Storage Utilization
by Logical Group - Reports subwindow in
the web client.
CAUSE: Either too many storage
subsystems have been selected, or the size
of the memory heap used by the Device
Manager server is too small.
SOLUTION: Decrease the number of storage
subsystems selected in the Storage Utilization by
Host - Reports subwindow or Storage Utilization
by Logical Group - Reports subwindow, and then
display a report. Alternatively, increase the size
of the memory heap used by the Device Manager
server to allow reports to be displayed.
The size of the memory heap can be changed as
follows.
1 Edit the Server.ini file, which is in the
following folder, to change the memory heap
size:
<Device Manager server
installation folder>\Server
2 Open the Server.ini file in a text editor,
and then change the value of
JVM_XOPT_HEAP_MAX to the value
calculated below, in MB. The default value is
256 MB. If the result of the following formula
is already smaller than 256 MB, then no
changes are needed.
The format is as
follows:JVM_XOPT_HEAP_MAX=-Xmxsetting-
valuem
setting-value = (0.0145 x number-of-
LUNs-displayed + 0.00165 x number-of-
WWNs-displayed) x N
(15000 x number-of-LUNs-displayed +
1700 x number-of-WWNs-displayed) x
number-of-users
number-of-LUNs-displayed: Total number of
LUNs displayed per host (not the number of
LUNs set for the storage subsystem)
number-of-WWNs-displayed: Total number of
WWNs displayed per LUN
number-of-users: Number of users using the
report feature concurrently.
3 After you change the Server.ini file,
restart the Device Manager server as follows:
Select Start, Programs, XP Command View
AE, Device Manager, and then Stop Server.
After the Device Manager server has been
stopped, select
Start, Programs, XP
Command View AE, Device Manager, and
then Start Server.
