"HA Group Notification from node1 (SNAPMIRROR SYNCHORONOUS EXCEPTION: Splitter critical threshold breached [OWM]) NOTICE" alert we received recently. However, we don't find any error on the snapmirror sync. All synced normally.
I tried to find more information about how this Splitter work in snapmirror. but seems fewer information for public.
I can only found "The splitter sends the I/O to both primary and secondary storage systems over the interconnect replication network." on the site.
My question is
1. How does the splitter work in snapmirror?
2. In what circumstances that splitter threshold will be breached?
3. What is the splitter threshold? where I can print the policy out? Seems it can be turn on/off only?
4. How to troubleshoot if we encounter such error for splitter?
