The comparative voltage level at the switchback point is a pretty good indication of the battery condition, and I think that could be used to trigger an "I need a new battery" email message well ahead of an unexpected total fail shutdown. I have a 20kw nat gas fired standby generator thats typically live in 5 seconds since the Mrs...

...1) Using "shared discs" (global devices). 2) Using "non-shared discs" (local devices). - The solution (1) is more simple, and we can use the HAStoragePlus resource type that we can found in the SC 3.2 installation. And as the data are "unique", i mean, in a failover/switchback scenario the "same" disc will be used in one or another host, the practical purpose is clear. The HOWTO for ZFS/NFS HA using shared discs (global devices), can be found here: Sun Cluster 3.2 installation: http://www.posix.brte.com.br/blog/?p=71 HA procedure for shared discs: http://...

...ple test it in this test environment.... A) Then I can deal with the index filesystem in one of two ways: 1) Make it local OR 2) NFS import it from the production DC server Comments as to which is best? I have used #1 before...which caused some temporary unhappiness with the switchover and switchback....during which time the index is badly wrong and DC auto-rebuilds it... B) Is there anything else I should do/not do? C) Any ugliness that will surface in this testing lashup but isn't important? -- ==== Stewart Dean, Unix System Admin, Henderson Computer Resources Center of Bard Colleg...
