VMM - Selective Restore of a Rapid Provisioned HA VM Smart Copy Fails With Error You cannot perform a selective restore operation on VM components that are on volumes without mount points. The selective restore operation uses file copy operations that requires the volume to have a mount point. The files are in \\?\{GUID} format. Smart Copy is Disabled for Cluster Shared Volumes The Smart Copy feature is disabled for Cluster Shared Volumes when: • Components for Hyper-V writer and SQL writer are on the same CSV. • SQL components are on the same CSV, but no SQL instance is owned by the current node. Networking This section contains information about network and firewall configuration, and general networking constraints. Using the HPC Server with Broadcom Ethernet NICs When setting up systems equipped with Broadcom Ethernet NICs to be used as HPC base or compute nodes with iSCSI storage, you might find that the Broadcom card does not accept the IQN string set for it by the HPC server. This failure will cause login failures when the node attempts to boot from its iSCSI volume, because the HPC head node configures the iSCSI boot volumes with IQN-based ACLs. To resolve this issue, change the BIOS setting on the Broadcom card and use a template string in the HPC settings when you configure the node template, as shown in the following procedure: 1. Start the HPC iSCSI Settings App from the Start Menu, click Start → All Programs → EqualLogic → HPC iSCSI Provider Settings. 2. Click Create new volumes with open ACLs. This option allows any initiator to log in to the volume. Windows Firewall Settings on Failover Cluster If you are using the native Windows firewall on your failover cluster and you want to use the Dell EqualLogic Multipath I/O DSM, you must configure your firewall to allow ICMP echo requests (pings) for ICMPv4 and ICMPv6. The installation procedure detects the firewall and gives you the option to amend your firewall configuration automatically. Use the iSCSI Initiator Properties Page Extension to verify that Multipath I/O is working correctly. If you do not configure the firewall automatically at installation time but you still want to use multipathing, you must configure your firewall manually to allow ICMP requests. The following command-line examples show typical firewall configuration rules: netsh advfirewall firewall add rule name="Dell EqualLogic MPIO Ping IPv4" dir=in action=allow description="Dell EqualLogic MultiPath I/O Ping rule" enable=yes profile=any localip=any remoteip=any protocol=icmpv4 netsh advfirewall firewall add rule name="Dell EqualLogic MPIO Ping IPv6" dir=in action=allow description="Dell EqualLogic MultiPath I/O Ping rule" enable=yes profile=any localip=any remoteip=any protocol=icmpv6 Refer to the documentation for your version of the Windows operating system for instructions on how to configure a firewall. Network Folder Repository for Smart Copy Backup Documents When you run ASM/ME on a Windows failover cluster, you must specify a shared network folder as a repository for the Smart Copy backup documents. Each node in the cluster must be able to access the folder. In addition, if you are sharing a PS Series group between several failover clusters, each cluster must have its own shared network folder. You cannot use a single shared network folder between multiple clusters for storing backup documents. iSCSI Initiator This section contains general constraints pertaining to the iSCSI initiator. 6 Dell EqualLogic Host Integration Tools for Microsoft Edition Version 5.3 Release Notes
