Dell PowerProtect Cyber Recovery 19.13 Installation Guide

Changing the SELinux context

After you install the Cyber Recovery software and the Docker components, change the SELinux context if necessary.

About this task

In an SELinux environment, the Cyber Recovery software might not start after a reboot due to unlabeled context type and custom policies.

NOTE: This procedure does not apply to a Cyber Recovery virtual appliance deployment. By default, the AppArmor application is installed in a Cyber Recovery virtual appliance deployment as a mandatory access control mechanism.

Steps

  1. Change the SELinux context: 
    chcon -u system_u -t bin_t /opt/dellemc/cr/bin/cradmin
chcon -u system_u -t bin_t /opt/dellemc/cr/bin/crcli
chcon -u system_u -t bin_t /opt/dellemc/cr/bin/crsetup.sh
  2. Reboot the system.

    The following is an example of the SELinux context: 

    root@hostname $ ls -Z /opt/dellemc/cr/bin/
-rwxr-----. root root system_u:object_r:bin_t:s0 cradmin
-rwxr-----. root root system_u:object_r:bin_t:s0 crcli
-rwxr-----. root root system_u:object_r:bin_t:s0 crsetup.sh
