  • Page 21: About Spares, Related Topics

    A best practice is to designate spares for use if disks fail. Dedicating spares to vdisks is the most secure method, but it is also expensive to reserve spares for each vdisk. Alternatively, you can enable dynamic spares or assign global spares. HP P2000 G3 MSA System SMU Reference Guide...

    For example, a payroll volume could be mapped with read-write access for the Human Resources host and be masked for all other hosts. An engineering volume could be mapped with read-write access for the Engineering host and read-only access for other departments’ hosts. HP P2000 G3 MSA System SMU Reference Guide...

  • Page 24: About Volume Cache Options, Related Topics, Using Write-back Or Write-through Caching

    P2000 G3 MSA System models use Unified LUN Presentation (ULP), which can expose all LUNs through all host ports on both controllers. The interconnect information is managed in the controller firmware. ULP appears to the host as an active-active storage system where the host can choose any available path to access a LUN regardless of vdisk ownership.

  • Page 26: About Managing Remote Systems, Related Topics, About The Snapshot Feature

    About managing remote systems You can add a management object to obtain information from a remote storage system. This allows a local system to track remote systems by their network-port IP addresses and cache their login credentials — the user name and password for a manage-level user on that system. The IP address can then be used in commands that need to interact with the remote system.

    Or you can choose to include the modified data since the snapshot was taken, which will revert the data on the master volume to the current snapshot. Snap Pool-1 Figure 2 Rolling back a master volume HP P2000 G3 MSA System SMU Reference Guide...

  • Page 28: About The Volume Copy Feature, Related Topics

    Snapshot operations are I/O-intensive. Every write to a unique location in a master volume after a snapshot is taken will cause an internal read and write operation to occur in order to preserve the snapshot data. If you intend to create snapshots of, create volume copies of, or replicate volumes in a vdisk, ensure that the vdisk contains no more than four master volumes, snap pools, or both.

Volume Shadow Copy Service (VSS) enables host-based applications to manage snapshots. For more information, see the VDS and VSS hardware provider documentation for your product. About RAID levels The RAID controllers enable you to set up and manage vdisks, whose storage may be spread across multiple disks.

  • Page 82: Restarting Or Shutting Down Controllers, Restarting

    When a disk becomes a leftover, the following changes occur: • The disk’s health becomes Degraded and its How Used state becomes LEFTOVR. • The disk is automatically excluded from the vdisk, causing the vdisk’s health to become Degraded or Fault, depending on the RAID level.

  • Page 83: Shutting Down, Testing Event Notification, Expanding A Vdisk

    Expansion can take hours or days to complete, depending on the vdisk’s RAID level and size, disk speed, utility priority, and other processes running on the storage system. You can stop expansion only by deleting the vdisk. Before starting a vdisk expansion, read the white paper “HP P2000 G3 MSA Best Practices” at http://h20195.www2.hp.com/v2/GetPDF.aspx/4AA3-2141ENW.pdf.

    Figure 4 Intersite and intrasite replication sets Remote replication uses snapshot functionality to track the data to be replicated and to determine the differences in data updated on the master volume, minimizing the amount of data to be transferred. Snapshots created by the remote replication process are a special form called replication snapshots, which do not count against snapshot license limits.

    The figure above illustrates initial, delta, and queued replications: • Initial replication: When the first replication is initiated, a snapshot of the primary volume is taken and every block of data is then copied to the secondary volume. When the copy is complete, the first snapshot is taken on the secondary volume, creating the first sync point.

Remote replication can operate without Snapshot being enabled; however, to get the most out of remote replication, it is recommended to enable both features. Normally, replication snapshots are not accessible to hosts. However, if Snapshot is enabled, a replication snapshot can be exported for use as a standard snapshot.
