How to boot gracefully from SAN after power failure
Posted on 2006-06-24
I have a server that boots from an EMC AX100 storage array. Both are connected to a UPS. After a power failure, both the EMC and the server boots at the same time, but the server cannot boot before the SAN has finished booting. How do I configure the server to wait until the EMC is up to start booting?
Related to the above, when the batter runs down to below a threshold, I want the EMC and the server to both shut down gracefully. The problem is, if I shut down the EMC first, the server will crash; if I shutdown the server first, I have no way of shutting down the EMC since the server is connected to the UPS and not the EMC. How do people do this?
