Re: What to do with HP-UX while rebooting EVA 5000

Hi,

If you are having a planned downtime for your storage the best method is to shutdown the servers which is connected to the eva for avoiding unexpected I/O.

Otherwise if you know the lun details using by the vg presented from the respective strorage. unmount the filesystem and deactivate the vg.

Before doing both these activity it is always best to have atleast the backup of vg vgexport) vgdisplay -v output and the luns wwn id.
So that after storage is online verify the lun wwn id and then activate the vg, mount the fs.

Like i said, we have more than one EVA, some of these servers are running other applications as well, that requires 100% uptime, so shutdown of the server can't be done untill everything else is done.

What about unmounting and removing the shares, and take them back up once the eva is online again? It takes some time, but i guess its the most secure and easy way?
