1. Issue RAID 1 and RAID 10 are both reported as RAID1_0 and are referred to as mirrored In the Gateway solution the PowerPath application logs an error Cluster resources may cause errors when you enable Single Instance Storage SIS ona PowerVault NX1950 cluster The Microsoft Management Console hangs during an operation Inconsistency between the slot number displayed in Microsoft Management Console and PowerVault Modular Disk Storage Manager Quorum disk is created automatically from the available disks In the Integrated solution password protected PowerVault MD3000 arrays are not supported Microsoft Services for NFS does not validate the domain name Setting quota limit that is larger than the LUN size does not display an error message In the PowerVault MD3000 storage array new LUNs cannot be created in a disk group Mounting shared volumes using network file system NFS displays an error in Linux clients Unauthenticated users can configure storage with Dell EMC arrays Description You have an option to create either a RAID 5 ora mirrored LUN When you create a mirrored LUN the default is two disks which is actually striping with mirroring without parity and not a mirrored LUN In the Gateway solution you may see a PowerPath error after you upgrade from the Windows Unified Data Storage Server 2003 Standard Edition to the Enterprise Edition2. The API allocates a safe buffer zone during the estimation of the maximum size of the RAID group due to the required 5 7 overhead of the RAID group Anew RAID group with additional disks may have been created In Gateway solutions actual After a successful LUN creation the reported LUN size is smaller than the Verify maximum allowed LUN size through LUN extension Size is smaller requested LUN size from the Share and Storage Management wizard Navisphere Manager than the requested size The API allocates a safe buffer zone during the estimation of the maximum LUN size The maximum LUN size also depends on the RAID type The overhead is approximately 5 7 of the LUN size For example in a LUN of size 100 GB 2 TB is allocated to overhead Upgrade Issues Table 1 5 provides a list of issues you may encounter during an upgrade and the possible workaround or solution Table 1 5 Upgrade Issues Issue Description Workaround Solution If Firewall is enabled during If the Windows firewall is enabled during upgrade from Disable the firewall before starting the upgrade upgrade it may cause issues Windows Unified Data Storage Server 2003 Standard Edition to Windows Unified Data Storage Server 2003 Enterprise Edition the Microsoft iSCSI Software Target console fails Importing Virtual Disks If you do not unassign the LUNs from a system correctly You must clear the SCSI reservation on the virtual disks before re
