I wonder if it would be possible to script a lun resize on the san level, with a set % increase.

I wonder if it would be possible to script a lun resize on the san level, with a set % increase.

Works great! Also email or sms notifications are possible. We’re using a VMFS check within Nagios. Works great! Also email or sms notifications are possible.

What I need is to monitor the free space on the VMFS volume...any tips? The only thing I have found are some scripts with scant documentation from the creator.

There's 2 5 MB pad files in each transaction log dir on the Exchange server. If the DB engine determines that the disk is out of space it deletes the files, writes out the pages in memory waiting to go into the transaction log(s) and then unmounts the databases that are affected. I wonder if VMWare could do something similar to bring down a system cleanly? Maybe suspend the VM? MS Exchange automatically does something similar.
