showsys (System info)

Help page

showsys - Show system information.

    showsys [options]

    The showsys command displays the HP 3PAR Storage system properties such as
    a system name, serial number, and system capacity information.

    Any role in the system

        Specifies that more detailed information about the system is displayed.

        Specifies that the system parameters are displayed.

        Displays the system fan information.

        Displays the system capacity information in MB (1024^2 bytes).

        Displays the system capacity information broken down by domain in MB
        (1024^2 bytes).

        Displays the system descriptor properties.

    -devtype FC|NL|SSD
        Displays the system capacity information where the disks must have a
        device type string matching the specified device type; either Fast
        Class (FC), Nearline (NL), Solid State Drive (SSD). This option can
        only be issued with the -space option.


    See setsys command for information on setting the threshold parameters
    indicated by the Value column in the output for showsys -param.

    In the output for showsys -param, (from configured settings) indicates that
    the system parameters displayed have been successfully read from the
    Persistent Repository (PR). If the PR is not available (most likely because
    of problems with the admin volume), the output reads (from default settings)
    and the values displayed would indicate the system defaults. When (from
    default settings) is displayed, system parameters cannot be updated.

    If the VVRetentionTimeMax is 0, then the volume retention time in the system
    is disabled.

    For the system capacity information, there might be some overlaps among
    Volumes, System, and Failed Capacities.

    The following example displays the system descriptor properties of a HP 3PAR
    storage system:

FF3_VMW_AO_03        Name: this is the lun name
4194304              Size: This is the number to 4tb
8388608              Size: 8tb

Move volume to another CPG using tunevv

Assuming I want to move a virtual volume (VV12_AO) to another new CPG (FC_r6):

tunevv usr_cpg FC_r6 VV12_AO

The logical disks used for user space are moved to CPG FC_r6 for virtual volume VV12_AO If you want to move the VV regions only use:

tunevv usr_cpg FC_r6 -src_cpg FC_r5 VV12_AO

Assuming I want to move a snapshot volume (VV12_AO) to another new SnapCPG (FC_Snap):

tunevv snp_cpg FC_Snap VV12_AO

Unfortunatly you will have to run both commands seperatly. As of the documentation they can't be combined.
