DPM 2007 Connecting a new Hard Disk RRS feed

  • Question

  • Hi,

    I have a virtual machine that is connected to ISCSI target.

    There is something faulty about the NAS so im going to change it with a new one.

    I keep the data for 30 days.

    My question is: Is it possible to add the new disk and start backup the data to that disk and disable the old disks?

     

    LA.

  • Hi,

    This company does have 3 different ISCSI target 5000GB, 2500GB, 2600GB.

    Im planning to make one ISCSI target about 15TB in the new NAS.

    Is that possible or do i have to create three ISCSI target with the same size so that DPM will able to sync?

    Thanks,

    LA

  • There is no need to have a matching number or size of LUNS. You just run a migration of each old iSCSI LUN in turn to the new LUN. They will just fill up the remaining empty space.

    However i don't know if there is any issue (techincal or performance) with having a single LUN that size. I'm pretty sure there is not, but best to get confirmation from one of the gurus.

  • Hi Alex,

     

    I have another machine that is running on 16 TB disk (which is suppose to be the maximum that windows GPT drive can take and also the maximum that you can extend a drive in ReadyNas). And its running without any problems.

  • Hi Alex,

    I migrated the data to the new disk and i will monitor the old disks... they should be empty by time.

    Thanks for your help.
