  • storage raid-options show

    Display RAID options

    Availability: This command is available to cluster administrators at the admin privilege level.

    Description

    The storage raid-options show command displays information about all the RAID options in a cluster. The options are described in the storage raid-options manual page.

    Parameters

    { [-fields <fieldname>,…​]

    If you specify the -fields <fieldname>, …​ parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.

    | [-instance ] }

    If you specify the -instance parameter, the command displays detailed information about all fields.

    [-node {<nodename>|local}] - Node

    Selects information about all the RAID options on the specified node.

    [-name <text>] - Option Name

    Selects information about the RAID options that have the specified name.

    [-value <text>] - Option Value

    Selects information about all the RAID options that have the specified value.

    [-recommended-value <text>] - Recommended Value

    Selects information about all the RAID options that have the specified recommended value.

    [-constraint <text>] - Option Constraint

    Selects information about all the RAID options that have the specified constraint. The 'constraint' field indicates the expected setting for a RAID option across both nodes of an HA pair. The possible values are:

    • none - no constraint on the value of this RAID option; nodes can have different values

    • same_preferred - the same value should be used on both nodes of an HA pair, otherwise the next takeover may not function correctly

    • same_required - the same value must be used on both nodes of an HA pair, otherwise the next takeover will not function correctly

    • only_one - the same value should be used on both nodes of an HA pair. If the values are different and a takeover is in progress, the value of the RAID option on the node that is taking over will be used

    • unknown - no information about constraints for this RAID option

    Examples

    The following example shows the RAID scrub settings for a node named node1:

    cluster1::> storage raid-options show -node node1 -name raid.scrub*
                                                   Current      Recommended
    Node     Option                                Value        Value         Constraint
    -------- ------------------------------------- ------------ -----------   -----------
    node1    raid.scrub.perf_impact                low          low           only_one
    node1    raid.scrub.enable                     on           off           none
