  • Page 39: Cluster Administration

    4 Cluster administration One important feature of HP StorageWorks P4000 G2 Unified NAS Gateways is that they can operate as a single node or as a cluster. This chapter discusses cluster installation and management issues. Cluster overview Up to eight server nodes can be connected to each other and deployed as a no single point of failure (NSPOF) cluster.
  • Page 40: Cluster Groups

    • FTP file share resources • iSCSI resources Cluster groups Cluster resources are placed together in cluster groups. Groups are the basic unit of failover between nodes. Resources do not fail over individually; they fail over with the group in which they are contained. Virtual servers A virtual server is a cluster group that consists of a static IP Address resource and a Network Name resource.
  • Page 41: Cluster Planning

    Cluster planning Successful cluster planning includes: • Storage planning • Network planning • Protocol planning Storage planning For clustering, a basic disk must be designated for the cluster and configured as the Quorum disk. Additional basic disks are presented to each cluster node for data storage as physical disk resources. The physical disk resources are required for the basic disks to successfully work in a cluster environment, protecting it from simultaneous access from each node.

    NOTE: AppleTalk is not supported on clustered disk resources. AppleTalk requires local memory for volume indexing. On failover events, the memory map is lost and data corruption can occur. Cluster groups and resources, including file shares The Failover Cluster Management tool (Start > Administrative Tools > Failover Cluster Management) provides complete online help for all cluster administration activities.
  • Page 44: Load Balancing

    Load balancing The creation of separate cluster groups for each virtual server provides more flexibility in balancing the processing load on the cluster between the two nodes. Each cluster group can be assigned to a cluster node using the preferred owner parameter. For example, if there are two cluster groups, the cluster could be set up to have the first cluster group owned by Node A and the second cluster group owned by Node B.

    Creating a cluster printer spooler Printer spoolers should be created in a separate group dedicated to this purpose for ease of management. For each printer spooler, a physical resource is required to instantiate the print spooler resource. In some cases, dedicated physical resources are not available and hence sharing of the physical resource among other members of the group is acceptable, remembering that all members of a group are managed as a unit.

    excluded from the possible owners list to prevent a resource from coming online on a particular node. Lastly the preferred owners list can be ordered, to provide an ordered list of failover nodes. Using these tools, the failover of resources can be controlled with in a multinode cluster to provide a controlled balanced failover methodology that balances the increased work load.
  • Page 50: Powering Up The Cluster

    The power down process is divided into two main steps: Shutting down the cluster nodes Removing power from the cluster nodes The sequence of these steps is critical. The devices must be shut down before the storage subsystem. Improperly shutting down the nodes and the storage subsystem causes corruption and loss of data. CAUTION: Before powering down the cluster nodes, follow the proper shutdown procedure as previously illustrated.

Extend volumes using Disk Management The Disk Management snap-in provides management of hard disks, volumes or partitions.
  • Page 73: Volume Shadow Copies

    • You cannot extend striped volumes, mirrored volumes, or RAID 5 volumes. For more information, see the Disk Management online help. Volume shadow copies NOTE: Select storage systems can be deployed in a clustered as well as a non-clustered configuration. This chapter discusses using shadow copies in a non-clustered environment.
  • Page 74: Identifying The Volume

    Identifying the volume Shadow copies are taken for a complete volume, but not for a specific directory. Shadow copies work best when the server stores user files, such as documents, spreadsheets, presentations, graphics, or database files. NOTE: Shadow copies should not be used to provide access to previous versions of application or e-mail databases.
  • Page 75: Identifying The Storage Area

    The minimum amount of storage space that can be specified is 350 megabytes (MB). The default storage size is 10 percent of the source volume (the volume being copied). If the shadow copies are stored on a separate volume, change the default to reflect the space available on the storage volume instead of the source volume.
  • Page 76: Mounted Drives

    If defragmenting volumes on which shadow copies are enabled, use a cluster (or allocation unit) size of 16 KB or larger. Using this allocation unit size reduces the number of copy outs occurring on the snapshot. Otherwise, the number of changes caused by the defragmentation process can cause shadow copies to be deleted faster than expected.
  • Page 77: The Shadow Copy Cache File

    Figure 29 System administrator view of Shadow Copies for Shared Folders The shadow copy cache file The default shadow copy settings allocate 10 percent of the source volume being copied (with a minimum of 350 MB), and store the shadow copies on the same volume as the original volume. (See Figure 30).
  • Page 78: Enabling And Creating Shadow Copies

    Figure 31 Shadow copies stored on a separate volume The main advantage to storing shadow copies on a separate volume is ease of management and performance. Shadow copies on a source volume must be continually monitored and can consume space designated for file sharing. Setting the limit too high takes up valuable storage space. Setting the limit too low can cause shadow copies to be purged too soon, or not created at all.
  • Page 79: Viewing A List Of Shadow Copies

    NOTE: After the first shadow copy is created, it cannot be relocated. Relocate the cache file by altering the cache file location under Properties prior to enabling shadow copy. See “Viewing shadow copy properties” on page 79. Viewing a list of shadow copies To view a list of shadow copies on a volume: Access Disk Management.
  • Page 80: Redirecting Shadow Copies To An Alternate Volume

    CAUTION: Use caution when reducing the size limit for all shadow copies. When the size is set to less than the total size currently used for all shadow copies, enough shadow copies are deleted to reduce the total size to the new limit. A shadow copy cannot be recovered after it has been deleted. Redirecting shadow copies to an alternate volume IMPORTANT: Shadow copies must be initially disabled on the volume before redirecting to an alternate volume.
  • Page 81: Managing Shadow Copies From The Storage System Desktop

    Managing shadow copies from the storage system desktop To access shadow copies from the storage system desktop: The storage system desktop can be accessed by using Remote Desktop to manage shadow copies.

  • Page 82: Smb Shadow Copies

    NOTE: Shadow Copies for Shared Folders clients are not available for HTTP, FTP, AppleTalk, or NetWare shares. Consequently, users of these protocols cannot use Shadow Copies for Shared Folders to independently retrieve previous versions of their files. However, administrators can take advantage of Shadow Copies for Shared Folders to restore files for these users.
  • Page 83: Nfs Shadow Copies

    Figure 33 Client GUI When users view a network folder hosted on the storage system for which shadow copies are enabled, old versions (prior to the snapshot) of a file or directory are available. Viewing the properties of the file or folder presents users with the folder or file history—a list of read-only, point-in-time copies of the file or folder contents that users can then open and explore like any other file or folder.
  • Page 84: Recovery Of Files Or Folders

    .@GMT-2003.04.29-04:00:00 Access to NFS shadow copy pseudo-subdirectories is governed by normal access-control mechanisms using the permissions stored in the file system. Users can access only those shadow copies to which they have read access at the time the shadow copy is taken. To prevent users from modifying shadow copies, all pseudo-subdirectories are marked read-only, regardless of the user's ownership or access rights, or the permissions set on the original files.
  • Page 85: Recovering An Overwritten Or Corrupted File

    Figure 34 Recovering a deleted file or folder Recovering an overwritten or corrupted file Recovering an overwritten or corrupted file is easier than recovering a deleted file because the file itself can be right-clicked instead of the folder. To recover an overwritten or corrupted file: Right-click the overwritten or corrupted file, and then click Properties.
  • Page 86: Backup And Shadow Copies

    Backup and shadow copies Shadow copies are only available on the network via the client application, and only at a file or folder level as opposed to the entire volume. Hence, the standard backup associated with a volume backup will not work to back up the previous versions of the file system. To answer this particular issue, shadow copies are available for backup in two situations.
  • Page 87: Folder Management

    NOTE: Select servers can be deployed in a clustered or non-clustered configuration. This section discusses share setup for a non-clustered deployment. Folder management Volumes and folders on any system are used to organize data. Regardless of system size, systematic structuring and naming conventions of volumes and folders eases the administrative burden. Moving from volumes to folders to shares increases the level of granularity of the types of data stored in the unit and the level of security access allowed.
