ax 150 configuration questions
i have recently purchased an ax 150
we will eventually have 6 servers hooked up to the SAn via a switch
i have two servers that i am testing with right now
i want to have our data reside upon the servers and have at a predetermined time a copy of the data be pushed up on the the SAN
i will have 1 server that has a lto-3 tape library hooked to it that i want to use to back up the data that was pushed up to the san
what do i have to do software wise to have the server push the data to the san ?
once there will i have to use snapshots to allow access to the data from the servers?
i am looking at having roughly 400gb of data
thanks

ok but is there something that can do this automatically? software wise?and i would have to have snapshots so my server that is doing backups can get to the data ?- Let me see if this is how you want to implent your solution.You have 6 servers that you will have data stored on their local drives and backed up to the AX150.Then you would like to backup the AX150 to a tape drive.If this is correct, you will need to assign each server a virtual disk and use a backup software to backup the files to the virtual disks. When you are ready to backup to tape, you will use Snapshots to create snap sessions of each of the AX150 virtual disks and assign the snapshot virtual disks to the backup server. It is possible to script the process, if you send me a private message, I'll send you a PDF I have on scripting the admsnap commands.

i am tring to get multiple servers hooked up to this unit nowhow do i find out the names of the snapshot sessions?the scripts on the backup machine only allow one drive to be active at a timewhat am i doing wrong ??- Use the -s parameter to specify a session name when you're starting a session on the source server. This way when you're on the mount server with -s you can specify which session you want to activate. Maybe by specifying this you can mount more than 1 snapshot.
I don't believe you can specify which drive letter is assigned for the mounting on the mount server. chrisrolke

okthanksi will try that today( i wish emc had better documentation for there product )- You select one yourself.
So on the source server you do a:
admsnap start -s sessionname_of_your_choice -o driveletter_of_lun_you_want_to_snap
Then on the backup server you do a:
admsnap activate -s sessionname_of_your_choice (where the 'sessionname_of_your_choice' is the one you previously selected)

For instance, if you're running Windows (you didn't specify the OS), with a C-drive and maybe a D-drive for internal scsi/raid drives, the SAN drive would show up in disk management as another drive where you'd initialize it, create a partition, format it and assign a drive letter.
You could do a 'drag and drop' from the server's own drive to the san drive, or use some software that can mirror or copy data at a scheduled time.
Keep in mind that each server will need it's own diskspace (they cannot share diskspace, unless they're clustered; which brings a whole other configuration setup into play).
