Parameter Description
sampleType This parameter is optional. The default value for
sampleType
is
all
.
v all
— Data for all three sample types are collected and
written to the same file.
v mostRecent — Statistics are recorded for the most
recent 50 resynchronization samples.
v longestSyncTime
— Statistics are collected for the most
recent 20 longest resynchronization samples.
v errors
— Statistics are recorded for the most recent 20
failed resynchronization samples. These samples
include a failure code.
recordLimit
This parameter is optional. The default value for record
limit is
no limit. The recordLimit must be greater than
0 and less than or equal to 90.
Notes
Statistics are captured for mirrored volumes in the Primary role. The statistics collected include the
following data:
v
Synchronization start time
v Synchronization type (manual or periodic)
v
Synchronization duration
v Number of bytes sent
v
Maximum write time (for a single write)
v
Minimum write time (for a single write)
v
Minimum synchronization data rate
v
Maximum synchronization data rate
v
Total write time
v
Repository utilization (%)
v
Recovery point age
During initial synchronization, statistics samples are captured approximately every 15 minutes.
The synchronization statistics are included in the support bundle.
Minimum Firmware Level
7.84
