The size of each log file (dlmwebagent[1-N].log) is 9900 KB
(approximately 10 MB). The size of the log files is calculated as
approximately 20 MB because two log files are created by default.
You can create a maximum of 16 log files depending on the setting in the
dlmwebagent.properties file. If you create 16 log files, the size of the
log files will be approximately 160 MB.
#6
The size of the log files for the dlmcfgmgr utility.
This size differs depending on the settings for the size of the log files for
the dlmcfgmgr utility (maximum size: 1954 MB (approximately 2 GB)).
v is obtained by using the following formula:
v = (w x 2) / 1024 [MB]
Where w is the size of the log files for the dlmcfgmgr utility (unit: KB,
default value: 1024).
The result is rounded up to MB.
#7
This is an approximate value when the default values are used for the
HDLM functions and when the number of paths is 256.
For details on the values of the HDLM functions, see
Table 3-71 The
Recommended and Default Values of Each Function on page 3-215 in
Setting Up the HDLM Functions on page 3-215 .
#8
The size of the configuration definition file.
y is obtained by using the following formula:
y = (2500 bytes x number-of-paths x 4) / 1024 / 1024 [MB]
The result is rounded up to MB.
#9
The size of the file that defines non-HDLM-managed disks.
z is obtained by using the following formula:
z = (20 bytes x number-of-non-HDLM-managed-disks x 4) / 1024 / 1024
[MB]
The result is rounded up to MB.
