When you do not use the HDLM GUI:
110MB + pMB
1 + qMB 2 + 1MB
„ When you do use the HDLM GUI:
110MB + 20MB + pMB
1 + qMB 2 + 1MB
1 This size depends on the settings for the log files. The maximum size is 30000MB.
When s is the error log file size (the default value is 9900) and m is the number of error log files (the default value is 2), this
value (p) can be calculated as follows:
p = (s x m) / 1024 (rounded-up integer) (units: MB)
2 This size depends on the setting for the trace files. The maximum size is 1000MB. When t is the trace file size (the default
value is 1000) and n is the number of trace files (the default value is 4), this value (q) can be calculated as follows:
q = (t x n) / 1024 (rounded-up integer) (units: MB)
3.1.5 Number of Paths Guaranteed in HDLM
Table 3.8 lists the number of LUs, number of paths per LU, and total number of paths
guaranteed in HDLM.
