No. Problem and cause Solution
2 PROBLEM: In Windows, reports are not
displayed when HTML is clicked in the
Storage Utilization by Host - Reports
subwindow or Storage Utilization by Logical
Group - Reports subwindow in 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:
installation-folder-for-the-
Device-Manager-server\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 > All Programs > XP Command
View AE > Device Manager > Stop Server.
After the Device Manager server stops, select
Start > All Programs
> XP Command View
AE > Device Manager > Start Server
