Table 36 Remote Copy I/O Statistics (continued)
Description Statistic
The number of journals at the primary storage system. M-JNL Total Number of Journal
The average transfer rate for journals in the primary storage system.
The unit is kilobytes per second. M-JNL Average Transfer Rate
The remote I/O process time on the primary storage system. The unit
is milliseconds. M-JNL Average RIO Response
The number of asynchronous remote I/Os per second at the secondary
storage system. R-JNL Asynchronous RIO count
The number of journals at the secondary storage system. R-JNL Total Number of Journal
The average transfer rate for journals in the secondary storage system.
The unit is kilobytes per second. R-JNL Average Transfer Rate
The remote I/O processing time on the secondary storage system.
The unit is milliseconds. R-JNL Average RIO Response
M-JNL
The data usage rate for master journals. The unit is percent. Data Used Rate
The metadata usage rate for master journals. The unit is percent. Meta Data Used Rate
R-JNL
The data usage rate for restore journals. The unit is percent. Data Used Rate
The metadata usage rate for restore journals. The unit is percent. Meta Data Used Rate
If the primary site in the multi-target configuration combines three XP Continuous Access Journal
sites, two or more mirrors are set in MCU. The following table describes data displayed in Initial
Copy and Asynchronous Copy in the Monitor Data box.
Table 37 I/O Statistics in Initial and Asynchronous Copy with Two or More Mirrors Set in MCU
Description Statistic
Initial Copy
The averate hit rate for all mirrors. The unit is percent. Initial Copy Hit Rate
Integrated value of transfer rate for initial copy operations in all mirrors. The
unit is kilobytes per second. Average Transfer Rate
Asynchronous Copy *
Integrated value of asynchronous remote I/Os in all mirrors M JNL Asynchronous RIO count
Integrated value of the number of journals in all mirrors M JNL Total Number of Journal
Integrated value of transfer rate for journals in all mirrors. The unit is kilobytes
per second. M JNL Average Transfer Rate
The average remote I/O process time of all mirrors. The unit is milliseconds. M JNL Average RIO Response
*: The asynchronous copy information per mirror is displayed in R-JNL. Note that it is impossible to reference the initial
copy information per mirror.
If the journal group attribute is Master/Restore, only the secondary storage system data is displayed.
The following table describes data displayed in Asynchronous Copy and R-JNL in the Monitor Data
box.
