Below are the minimum required vCenter User Account Permissions for an Avamar account in order to setup image level backups. EMC recommends as a best practice to setup a separate account for Avamar to use during the image-level backups. This is to assist with troubleshooting any problems with backups and to also help maintain a secure vCenter environment. In high-security environments, you can restrict the vCenter user account permissions required to configure and administer the Avamar VMware image backup and restore feature to all of the following:
The following is the procedure to Shutdown Avamar GSAN:
1. Log on to the system as user admin.
2. Load the ssh keys
3. Verify hfscheck and garbage collect are not running.
ps -eaf|egrep “gc_cron|cp_cron|hfscheck_cron”
If hfscheck is still running, run “hfscheck_kill” as user admin to kill it off.
If GC is still running, you will need to let it finish before continuing.
If CP is running, you will need to let it finish running.
4. Take a checkpoint (as dpn)
su – dpn
exit (Note..you should now be back to admin)
5. Stop the EMS and MCS
dpnctl stop ems
dpnctl stop mcs
6. Stop the GSAN
7. Verify avamar is shutdown
In this output it shows avamar is down:
dpnctl: INFO: gsan status: down
dpnctl: INFO: MCS status: down.
dpnctl: INFO: EMS status: down.
dpnctl: INFO: Scheduler status: down.
dpnctl: INFO: Maintenance operations status: suspended.
dpnctl: INFO: Unattended startup status: disabled.
dpnctl: INFO: [see log file “/usr/local/avamar/var/log/dpnctl.log”]
Now you can safely power off the hardware.
