The following information can be obtained.
-
snapshotVolumeId: Volume ID (uuid) of the S-VOL
-
snapshotVolumeName: Name of the S-VOL
-
snapshotVolumeNickname: Nickname of the S-VOL
-
statusSummary: Status summary of the S-VOL
-
status: Volume status
-
snapshotStatus: Snapshot status
It might take about one minute for snapshotStatus to transit. To confirm the transition of snapshotStatus, wait about one minute and then check again.
-
snapshotProgressRate: Progress rate of preparation for taking snapshots of, deleting, and restoring the S-VOL [%]
-
snapshotTimestamp: Time when recording of difference data started for the P-VOL at the time of snapshot creation
-
snapshotType: Snapshot type
-
snapshotConcordanceRate: Match rate between the volume and one newer generation of S-VOL or copy-source volume (P-VOL) [%]
-
isWrittenInSvol: Whether the volume has been written from the compute node (host)
-
vpsId: ID of the VPS to which the S-VOL belongs
-
vpsName: Name of the VPS to which the S-VOL belongs
-
qosParam: QoS-related parameter
-
upperLimitForIops: Upper limit for volume performance [IOPS]
-
upperLimitForTransferRate: Upper limit for volume performance [MiB/sec]
-
upperAlertAllowableTime: Alert threshold value for the upper limit of volume performance [sec]
-
upperAlertTime: The last time the upper limit of volume performance was continuously exceeded and the conditions for the alert threshold of the performance upper limit were met (UTC)
-
The matching rate of the S-VOL is handled as follows. Whether the generation is older or newer can be verified from snapshotTimestamp.
-
snapshotConcordanceRate [%] for the newest generation (S-VOL1) is the rate of matching with the P-VOL.
-
snapshotConcordanceRate [%] for the S-VOL2 is the rate of matching with the S-VOL3, which is one generation newer than the S-VOL2.
-
snapshotConcordanceRate [%] for the S-VOL3 is the rate of matching with the S-VOL1, which is one generation newer than the S-VOL3.
When data is written to the P-VOL, the matching rate of the S-VOL1 (newest generation) seemingly decreases because the data written to the P-VOL is assumed to be differential data. If data is written to an S-VOL, the matching rate of only the S-VOL decreases.
