Activating a software maintenance upgrade (SMU) does not cause previous versions of the SMUs, or the
package to which the SMU applies, to be automatically deactivated.
Note
Committing the Active Software Set
When a package is activated on the router , it becomes part of the current running configuration. To make the
package activation persistent across reloads, enter the install commit command in administration EXEC
mode. On startup, the designated shelf controller (DSC) of the secure domain router (SDR) loads the committed
software set.
If the system is restarted before the active software set is saved with the install commit command, the
previously committed software set is used.
Note
Rolling Back to a Previous Installation Operation
Although the term commit sounds final, the Cisco IOS XR software provides the flexibility to roll back the
selected package set to previously saved package sets. Each time a package is activated or deactivated, a
rollback point is created that defines the package set that is active after the package activation or deactivation.
The software also creates a rollback point for the last committed package set. If you find that you prefer a
previous package set over the currently active package set, you can use the install rollback command to
make a previously active package set active again.

Multiple Disks Support during Installations
In installations on platforms where Cisco IOS XR Software is supported, only a single disk is used as an install
device; that is, either disk0 or disk1. When multiple packages are installed on a single disk, it results in space
constraints. To resolve this space limitation, the disk supported for the install operations has been extended
to another disk called the disk1. When installing multiple packages, this feature enables you to choose between
disk0 and disk1.
To add packages to a specific disk name, use the install media command in the admin configuration mode.
RP/0/RSP0/CPU0: router (admin) # install media disk1
Restrictions
•
Before enabling the addition of disk1 through the install media command, the disk mirroring feature
should be explicitly disabled. For details regarding disk mirroring, see the Disk Mirroring chapter.
•
All single version packages should be installed into one disk; that is, either disk0 or disk1.
