4. In the tabs area, select the PiT tab. The following information is displayed for each PiT.
Table 82 Virtual Disk/VDG/Snapshot/VDG Snapshot PiT tab fields
DescriptionProperty
The row number.No
The name of a PiT.Name
The status of the PiT.
Status
• Init—The PiT is being created.
• Normal—The status of all the virtual disks from which the PiT is constructed
is normal. This includes an original virtual disk, the temporary virtual disk
created for the PiT, and any PiTs and snapshots between the original virtual
disk and the PiT in the hierarchy.
• Partial—The status of one of the virtual disks from which the PiT is construc-
ted is partial.
The current state of the PiT. Possible values:
State
• Create—The temporary virtual disk created to hold future modifications to
the virtual disk data is in the process of creation. The reallocation table is
not yet cleared.
• Normal— The temporary virtual disk completed initialization and is in a
normal operational state.
• Resync—The PiT is being deleted (or each of multiple PiTs in the case of a
VDG or VDG snapshot.). The modifications held in the temporary virtual
disk of the PiT (or each PiT) are being merged back into the entity that
would have received those modifications had the PiT not been created.
This may be the virtual disk or snapshot on which the PiT was created or
an earlier PiT on the same virtual disk or snapshot.
• Rollback—The virtual disk or snapshot on which the PiT (or each PiT in the
case of a VDG or VDG snapshot) was created, is in the process of rollback.
The PiT is being deleted without the modifications of the temporary virtual
disk being merged back into the entity that would have received those
modifications had the PiT not been created. For more information, see
“Navigating through snapshot hierarchies” on page 227.
• Absent—A transitional state in which PiT deletion (resync) is complete but
the VSM server is waiting for a final acknowledgement from the host before
it deletes the temporary virtual disks used for the deleted PiT.
• Instant Restore—The virtual disk or snapshot on which the PiT (or each PiT
in the case of a VDG or VDG snapshot) was created is performing an instant
restore. For more information, see “Restoring from snapshots” on page 230.
• Init—The reallocation table on the PiT temporary virtual disk is being created
and initialized.
The percentage progress of the resynchronization process that takes place
when the PiT is deleted.
Synchronization Level
When a PiT is deleted, the data from the temporary virtual disk that was created
for the PiT is merged back into the entity that would have received those
modifications had the PiT not been created, which may be the virtual disk or
snapshot on which the PiT was created or an older PiT on the same virtual disk
or snapshot.
The time at which the PiT was created.Creation Time
