Current/Max. Media Extent

The number of RAID volume (LD, LV, or partitions) currently associated with this Snapshot Container and the max. number of volumes allowed.

Inode Table Entry Size

Inode refers to the infrastructure table used to organize data differentials, differential locations, and relational information

Total Number of Inodes in all Media Extents Combined

Total number of inodes in all storage volumes allocated for a Snapshot Container.

Number of Inode Allocated

Number of inodes allocated for snapshot operation.

Number of Data Area Section in all Media Extents Combined

Number of Data Area Sections in all storage volumes allocated for a Snapshot Container.

Number of Data Area Section Allocated

Number of Data Area Sections consumed for the current snapshot operation.

Snapshot Set

LD/LV, Partition

The unique ID of the source volume this Snapshot Set is referring to.

Activated

A snapshot image has been created in the Snapshot Set.

Mount Status

Array status (the status of the RAID array that this Snapshot Set is referring to).

Data Block Size

Data blocks consumed by the Snapshot Images in this Snapshot Set.

Current Active Snapshot Image ID

The unique ID(s) of the currently activated Snapshot Image(s).

Snapshot Image

Activation Sequence Number

When a snapshot image is activated, it appears as a frozen image that can be mapped to a host LUN. The act of taking a snapshot image actually include creating and activating a snapshot image. The sequence number indicates the image’s positions among a series of snapshot images. 

Activated Actual Time

Indicates the time when the image was taken.

Last Modification Time

The last time when the source volume receives updates and differentials were added to a snapshot image.

Activation Schedule Time

Applies to Snapshot Scheduler. The time refers to when the scheduler creates and activates a snapshot image.

Total Number of Data Block Entries

The total number of data block entries reserved for a snapshot image.

Valid Data Block Entries already Filled

Numbers of data block entries consumed by storing data differentials.

Total Data Block Entries already Filled

Numbers of data block entries consumed by data differentials including valid and bad blocks.
