Check connectivity
Step 1. Connect to primary SynetoOS appliance via SSH as admin
ssh admin@<your_ip_address_or_hostname>
Step 2 (optional). Change into Solaris shell (in case you're directed to an unsupported shell)
un sh
Step 3. Get root privileges
sudo su -
Step 4. Check secondary Syneto reachability (replace <ip_address_syneto_target> with the correct information)
ping <ip_address_syneto_target>IMPORTANT
If the secondary Syneto does not respond to a ping, it is recommended to contact the network administrator to identify and resolve the connectivity issue.
Check free space
Step 1. Login to secondary SynetoOS GUI (replace <ip_address_syneto_target> with the correct information)
https://<ip_address_syneto_target>
Step 2. From the left menu, click on Dashboard
Step 3. Check if the target pool has free space available
IMPORTANT
If the used space is full, it's necessary to free up storage, or – better – expand the system by adding additional hard drives.
Compare the snapshots
Step 1. Login to secondary SynetoOS GUI (replace <ip_address_syneto_target> with the correct information)
https://<ip_address_syneto_target>
Step 2. From the left menu, click on Datastores
Step 3. Select the target datastore by clicking on the corresponding row
Step 4. Click on Snapshots
Step 5. Check the latest available snapshot
Step 6. Login to primary SynetoOS GUI (replace <ip_address_syneto_source> with the correct information)
https://<ip_address_syneto_source>
Step 7. From the left menu, click on Datastores
Step 8. Select the source datastore by clicking on the corresponding row
Step 9. Click on Snapshots
Step 10. Check if the latest snapshot on the target is present on the source
IMPORTANT
To verify that a snapshot has been successfully replicated to both systems, check the exact date and time (pay attention to any time zones).If the snapshot is not present, the datastore on the target system must be deleted ("How to delete a datastore in SynetoOS 4") and a new full backup must be replicated.
