• Make sure all QLogic Authentication Groups on the SAN have load
balancing enabled in the SAN/iQ CMC. If there is a mix, some have it
enabled and some don’t, then those that don’t might not connect to
their volumes
Expanding a SAN/iQ volume and extending an NTFS partition on
the iSCSI volume
• Both SAN/iQ volumes and NTFS volumes can be expanded or extended
dynamically. If space is running low on an NTFS volume, you will want to
first make the volume it is on larger. To expand the SAN/iQ volume,
simply edit it in the LeftHand CMC and give it a larger size. SAN/iQ will
immediately change the LUN size and layout data across the cluster
accordingly without affecting its availability. Once the SAN/iQ volume has
been expanded, the NTFS partition on that volume can be expanded with
the DISKPART utility. (See Microsoft KB #300415 and/or the
LeftHand SAN User’s Guide pages 353-355).
