Hi,

I want to add a iSCSI3-PR disk to VCS but unable to find any documented steps for it.

Any pointers appreciated.

Thanks

Hi Abhay,

Can you provide more details on what OS and what version of VCS you are using?  This should help to get the right person involved.

Thanks,
Wally

You mean, you want to setup IO-fencing ?

No, I just want to add a disk as a shared resource in VCS for which I was using ISCSI disk.

I am not sure if that can be used. Please let me know if this will work

The VCS product does support iSCSI disks.  It has resources to allow you to use iSCSI disks from Netapp arrays.  iSCSI disks from other arrays can be used with the DiskRes and Mount resources.

If you are using SFW-HA then SFW can hand iSCSI disks and allow them to be added into Dynamic disk groups for the cluster to use.

Thanks,
Wally

Thanks Wally,

I am not using SFW-HA, I am using VCS 5.1. Can you please direct me to some documentation which helps in adding ISCSI disks as resource in VCS 5.1 as a DiskRes or Mount resources.

There should be no diffrence in using ISCSI versus a FC array disk. Is the wizard you are running not detecting the volume you created on that disk?

You should be able create a mount resource in VCS to manage the volume. Once the resource is created setup your MountResName and/or Signature and then the MountPath. after that just setup the dependencies.

Note: For using LDM, your storage devices must be configured to use SCSI-2 disk reservations. SCSI-3 is not supported.
