Rollback Commands
compare
Syntax compare [to checkpoint2]
compare checkpoint1 to checkpoint2
Context admin>rollback
Description Platforms Supported: 7210 SAS-R6.
This command displays the differences between rollback checkpoints and the active operational
configuration, with source1 as the base/first file to which source2 is compared.
Parameters checkpoint1 to checkpoint2 — Specifies comparison information.
Default The defaults for source1 and source2 are context aware and differ based on the branch in which the
command is executed. In general, the default for source1 matches the context from which the com-
mand is issued.
• In the admin node: No defaults. checkpoint1 and checkpoint2 must be specified.
delete
Syntax delete checkpoint | rescue
Context admin>rollback
Description Platforms Supported: 7210 SAS-R6.
This command deletes a rollback checkpoint and causes the suffixes to be adjusted (decremented) for
all checkpoints older that the one that was deleted (to close the “hole” in the list of checkpoint files
and create room to create another checkpoint).
If “config redundancy rollback-sync” is enabled, a rollback delete will also delete the equivalent
checkpoint on the standby CF and shuffle the suffixes on the standby CF.
It is not advised to manually delete a rollback checkpoint (for example, using a "file delete"
command). If a rollback checkpoint file is manually deleted without using the "admin rollback
delete" command then the suffixes of the checkpoint files are NOT shuffled, nor is the equivalent
checkpoint file deleted from the standby CF. This manual deletion creates a “hole” in the checkpoint
file list until enough new checkpoints have been created to roll the “hole” off the end of the list.
Default none
Parameters checkpoint — An id from [1 ..max] indicating a specific rollback checkpoint (where max is the
highest checkpoint allowed/configured). A checkpoint of 1 indicates the rollback checkpoint file
(at the configured rollback-location) with “*.rb.1” as the suffix, 2 for file “*.rb.2”, etc.
