    Default How do I delete Logical Volumes?

    Hi there,

    I have recently been tasked with remote support of a pair of these iSCSI-R3 SANs.
    I've had a look round and it mainly seems pretty straight-forward.
    However, I've been asked to do some reconfiguration and I'm struggling a little, I assume it is something obvious that I am missing, or something that needs to be enabled from the console.

    I only have access via the web GUI.
    I have logged on, gone to Configuration and Volume Manager, selected the Volume group in the left hand pane and the Logical Volume list appears in the right hand pane.
    At this point they are all greyed-out and I have no option to do anything with them.
    I can create a new LV, which gives me a nice little red X to delete it with again(but no other options), but I can't do anything with the existing LVs.

    Please could someone point me in the right direction?

    I'm more a DSS user but your description of the UI matches... the greyed-out LVs are used by iSCSI targets, you need to remove the LV from the target (which may still exist afterwards).

    Once the LV is no longer in use, the UI should allow you to delete it.

    Default Aaaaaaaaaaaaaaargh!!! Help Please!!

    ** URGENT ** Please help me!

    OK, I figured out what was causing it, but have now made a massive mistake!

    I have deleted some LVs that I didn't want to. There are no snaphots.

    Is there any way I can recover them please?

    Just go to the Extended tools in the Console and select "Restore LVM VG ..." and select the last known good date and reboot.
    All the best,

    thanks Tom,

    is it possible to do that from the web interface, as I am about 100 miles away from the site.

    No, you will need to get the Firewall to let ports 22222 for SSH to get into the Console - see the SETUP -> administrator -> Function: Remote access for more details.
    All the best,
