DescriptionOperation Displayed
An operation for releasing a pair has been started at the
secondary storage system. The status of the pair will change
from HOLD to SMPL.
Status Change by RCU(HOLD to SMPL; Pairsplit-S Start)
The status of the S-VOL was changed to HOLD because of
a delta resync operation.
Status Change to HOLD
The storage system could not identify the type of the
operation.

History window notes
• The operation rows may not appear in chronological descending order. To sort the information
in descending (or ascending) order, click a heading.
• The history file always contains the most recent operations up to a maximum of 524,288
operations. Information older than seven days is not shown.
• If a failure occurred with two or more pairs at the same time, the number of pairs showing
Pairsplit-r(Failure) or Ready for Delta resync(Failure) may not match the actual number of pairs
in which the failure occurs.
• If a pair consists of LUSE volumes, the list shows only the top LDEV numbers of the LUSE
volumes.
• The copy time might not be shown in the Copy Time column, even though Paircreate Complete
or Pairresync Complete is shown in the Operation column. In such case, you can review the
copy time in the volume list in the Pair Operation window
Export operations history
Use the History window Export function to save operation history to a CSV file.
The following is an example of an exported text file.
(1) Data and time when the operation finished.
(2) Operation.
(3) Journal number
(4) Mirror ID
(5) LDKC number, CU number and LDEV number of the volume in the local storage system (LDKC : CU : LDEV).
(6) LDKC number, CU number and LDEV number of the volume in the remote storage system (LDKC : CU : LDEV).
(7) Extended consistency group number (used only with Continuous Access Journal Z). If no EXCTG, hyphens (--) display.
(8) Time taken for copying (from the start to the end of copying). Time is provided only when the operation (see (2))
is Paircreate Complete or Pairresync Complete
