Parameter Description
• The term repos
• A four-digit numerical identifier that you assign
to the repository virtual disk name
repositoryFullPolicy
Defines how snapshot image processing continues
if the snapshot image repository virtual disk is full.
You can choose to fail writes to the base virtual
disk (failBaseWrites) or delete (purge) the
snapshot images (purgeSnapImages). The default
action is
purgeSnapImages.
rollBackPriority
Determines whether system resources should be
allocated to the rollback operation at the expense
of system performance. A value of high indicates
that the rollback operation is prioritized over all
other host I/O. A value of low indicates that the
rollback operation should be performed with
minimal impact to host I/O. The default value is
medium.
repositoryFullLimit
The percentage of repository capacity at which
you receive a warning that the snapshot image
repository virtual disk is nearing full. Use integer
values. For example, a value of 70 means 70
percent. The default value is 75.
autoDeleteLimit
The maximum number of snapshot images that
you want to automatically delete if you have
selected to purge the snapshot images for the
repository full policy. The default value is 32.
Notes
Each snapshot group user label must be unique. You can use any combination of alphanumeric
characters, underscore (_), hyphen(-), and pound (#) for the user label. User labels can have a maximum
of 30 characters.
To create a snapshot group, you must have an associated repository virtual disk in which you store the
snapshot images. You can either use an existing repository virtual disk or create a new repository virtual
disk. You can create the repository virtual disk when you create the snapshot group. A snapshot group
repository virtual disk is an expandable virtual disk that is structured as a concatenated collection of up to
16 standard virtual disk entities. Initially, an expandable repository virtual disk has only a single element.
The capacity of the expandable repository virtual disk is exactly that of the single element. You can
increase the capacity of an expandable repository virtual disk by attaching additional standard virtual disks
to it. The composite expandable repository virtual disk capacity then becomes the sum of the capacities
of all of the concatenated standard virtual disks.
A snapshot group has a strict ordering of snapshot images based on the time that each snapshot image is
created. A snapshot image that is created after another snapshot image is a successor relative to that
