Initiate OBCP Cluster iSCSI Connection

Add Capacity to OBCP Cluster NAS

1. Insert hard disk with caddy into next available slot within NAS
2. Within the NAS Windows OS, open Dell Open Manage Server Administrator
   1. Initialize the new physical disk
   2. Reconfigure the virtual disk (RAID-6) to include the new disk
   3. Re-initialize the virtual disk to prepare for added capacity
3. Within the NAS Windows OS, open Windows Computer Management
   1. In Disk Management, extend the virtual disk volume to use the added capacity
   2. In iSCSI Software Management, go to Device and extended the virtual disk volume to use the added capacity
4. Within the cluster Ubuntu OS, prepare to extend the iSCSI partition and filesystem
   1. Kill any processes accessing the iSCSI interface
   2. Logout from the iSCSI connection and unmount the iSCSI filesystem (umount /dev/sdb1 - may require a restart)
   3. Within the Ubuntu GUI, open GParted and extend the partition stored on the NAS
   4. Log back into the iSCSI connection and remount the iSCSI filesystem (mount -a)
5. The cluster is now ready to use the additional storage capacity
