    Configuring pools using the CLI

    Configure custom pools

    Pools are the groups of drives on which you create storage resources. Configure pools based on the type of storage resource and usage that will be associated with the pool, such as file system storage optimized for database usage. The storage characteristics differ according to the following:

    • Type of drive used to provide the storage.
    • (dual-SP virtual deployments only) RAID level implemented for the storage.
    Note:  Before you create storage resources, you must configure at least one pool.

    The following table lists the attributes for pools:

    Table 1. Custom pool attributes
    Attribute
    Description
    ID
    ID of the pool.
    Name
    Name of the pool.
    Type
    Pool type. Valid values are:
    • Dynamic
    • Traditional
    Description
    Brief description of the pool.
    Total space
    Total storage capacity of the pool.
    Current allocation
    Amount of storage in the pool allocated to storage resources.
    Preallocated space
    Amount of storage space reserved in the pool by storage resources for future needs to make writes more efficient. The pool may be able to reclaim some of this space if total pool space is running low. This value equals the sum of the sizePreallocated values of each storage resource in the pool.
    Remaining space
    Amount of storage in the pool not allocated to storage resources.
    Subscription
    For thin provisioning, the total storage space subscribed to the pool. All pools support both standard and thin provisioned storage resources. For standard storage resources, the entire requested size is allocated from the pool when the resource is created, for thin provisioned storage resources only incremental portions of the size are allocated based on usage. Because thin provisioned storage resources can subscribe to more storage than is actually allocated to them, pools can be over provisioned to support more storage capacity than they actually possess.
    Note:   The system automatically generates an alert when the total pool usage reaches 85% of the pool's physical capacity. -alertThreshold specifies the alert threshold value.
    Subscription percent
    For thin provisioning, the percentage of the total space in the pool that is subscription storage space.
    Alert threshold
    Threshold for the system to send an alert when hosts have consumed a specific percentage of the subscription space. Value range is 50 to 85.
    Drives
    List of the types of drives on the system, including the number of drives of each type, in the pool. If FAST VP is installed, you can mix different types of drives to make a tiered pool. However, SAS Flash 4 drives must be used in a homogeneous pool.
    Number of drives
    Total number of drives in the pool.
    Number of unused drives
    Number of drives in the pool that are not being used.
    RAID level (physical deployments only)
    RAID level of the drives in the pool.
    Stripe length (physical deployments only)
    Number of drives the data is striped across.
    Rebalancing
    Indicates whether a pool rebalancing is in progress. Valid values are:
    • yes
    • no
    Rebalancing progress
    Indicates the progress of the pool rebalancing as a percentage.
    System defined pool
    Indication of whether the system configured the pool automatically. Valid values are:
    • yes
    • no
    Health state
    Health state of the pool. The health state code appears in parentheses. Valid values are:
    • Unknown (0) - Health is unknown.
    • OK (5) - Operating normally.
    • OK BUT (7) - Pool has exceeded its user-specified threshold or the system specified threshold of 85%.
    • Degraded/Warning (10) - Pool is operating, but degraded due to one or more of the following:
      • Pool has exceeded the user-specified threshold.
      • Pool is nearing capacity.
      • Pool is almost full.
      • Pool performance has degraded.
    • Major failure (20) - Dirty cache has made the pool unavailable.
    • Critical failure (25) - Pool is full. To avoid data loss, add more storage to the pool, or create more pools.
    • Non-recoverable error (30) - Two or more drives in the pool have failed, possibly resulting in data loss.
    Health details
    Additional health information. See Appendix A, Reference, for health information details.

    Indicates the state of an auto-delete operation on the pool. Valid values are:
    • Idle
    • Running
    • Could not reach LWM
    • Could not reach HWM
      Note:   If the auto-delete operation cannot satisfy the high water mark, and there are snapshots in the pool, the auto-delete operation sets the auto-delete state for that watermark to Could not reach HWM , and generates an alert.
    • Failed

    View storage profiles (physical deployments only)

    Storage profiles are preconfigured settings for configuring pools based on the following:

    • Types of storage resources that will use the pools.
    • Intended usage of the pool.

    For example, create a pool for file system storage resources intended for general use. When configuring a pool, specify the ID of the storage profile to apply to the pool.

    Note:  Storage profiles are not restrictive with regard to storage provisioning. For example, you can provision file systems from an FC or iSCSI database pool. However, the characteristics of the storage will be best suited to the indicated storage resource type and use.

    Each storage profile is identified by an ID.

    The following table lists the attributes for storage profiles.

    Table 4. Storage profile attributes
    Attribute
    Description

    • Traditional
    Description
    Brief description of the storage profile.
    Drive type
    Types of drives for the storage profile.
    RAID level
    RAID level number for the storage profile. Value is one of the following:
    • 1 - RAID level 1.
    • 5 - RAID level 5.
    • 6 - RAID level 6.
    • 10 - RAID level 1+0.
    Maximum capacity
    Maximum storage capacity for the storage profile.
    Stripe length
    Number of drives the data is striped across.
    Note:  For best fit profiles, this value is Best fit .
    Disk group
    List of drive groups recommended for the storage pool configurations of the specified storage profile. This is calculated only when the -configurable option is specified.
    Maximum drives to configure
    List of the maximum number of drives allowed for the specified storage profile in the recommended drive groups. This is calculated only when the -configurable option is specified.
    Maximum capacity to configure
    List of the maximum number of free capacity of the drives available to configure for the storage profile in the recommended drive groups. This is calculated only when the -configurable option is specified.
    Note:   The show action command explains how to change the output format.

    -id
    Type the ID of a storage profile.
    -driveType
    Specify the type of drive.
    -raidLevel
    Specify the RAID type of the profile.
    -traditional
    (Available only for systems that support dynamic pools) Specify this option to view the profiles that you can use for creating traditional pools. To view the profiles you can use for creating dynamic pools, omit this option.
    -configurable
    Show only profiles that can be configured, that is, those with non-empty drive group information. If specified, calculates the following drive group information for each profile:
    • Disk group
    • Maximum drives to configure
    • Maximum capacity to configure

    If the profile is for a dynamic pool, the calculated information indicates whether the drive group has enough drives for pool creation. The calculation assumes that the pool will be created with the drives in the specified drive group only.

    Configure a dynamic pool

    You can configure dynamic pools for all-Flash models of Unity running OE version 4.2.x or later. New pools created for these models are dynamic pools by default. Dynamic pools implement advanced RAID technology. In dynamic pools, a RAID group is spread across drive extents in multiple drives. The required spare space is also spread across drive extents in multiple drives. When a drive fails, the extents on the failed drive are rebuilt to spare space extents within the pool.

    When you configure dynamic pools, you can select different capacity drives from different drive groups with the same Flash drive types to create a tier. The total drive count of the drive type must be at least the stripe width plus one. For example, the total drive count for a RAID 4 + 1 group must be at least 6.

    Step 2: Configure the traditional pool

    Configure a traditional pool with the specified profile. Make sure you set -type to traditional and that the -drivesNumber is a multiple of the RAID group width. 

                              uemcli /stor/config/pool create -name test -diskGroup dg_34 -drivesNumber 9 
-storProfile tprofile_2 -type traditional

    The show action command

    The show action command displays a list of objects that exist on the system and the attributes of those objects. You can specify an object qualifier to view the attributes for a single object. The show action command provides qualifiers for changing the display of the output, including the format and the attributes to include. The available output formats are name-value pair (NVP), table, and comma-separated values (CSV).

    Format
    uemcli [<switches>] <object> [<object qualifier>] show [{-detail | -brief | -filter <value>] [-output {nvp | table [-wrap] | csv}]
    Action qualifier
    Qualifier
    Description
    -output|-o
    Specify the output format. Value is one of the following:
    • nvp — The name-value pair (NVP) format displays output as name=value. Name-value pair format provides an example of the NVP format.
    • table — The table format displays output as a table, with column headers and rows. By default, values that are too long to fit in a column are cut off. Add -wrap after the table qualifier, separated by a space, so that the values wrap. Table format provides an example of the table format.
    • csv — The comma-separated values (CSV) format is similar to the table format, but the names and values are separated by commas. Comma-separated values format provides an example of the CSV format.
    -detail
    Display all attributes.
    -brief
    Display only the basic attributes (default).
    -filter
    Comma-separated list of attributes which are included into the command output.

    Example

    The following command modifies the set of attributes in the show action output. For example, if you add -filter "ID,ID,ID,ID" to the command, in the output you will see four lines with the "ID" attribute for each listed instance: 

                          1:  ID = la_0
    ID = la_0
    ID = la_0
    ID = la_0
    uemcli /net/nas/server show -filter “ID, SP, Health state, ID, Name”
