Displays pool information for Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, and active flash for mainframe.

Syntax

raidcom get dp_pool [-key <keyword> [-fx] 
   [-pool {<pool_id> | <pool naming>} ]] [-pcap]

Options and parameters

[-key <keyword> [-fx]]

Specifies the display keyword. Specify opt as <keyword>. If you specify opt, information about Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe pool is displayed.

If you specify the -fx option, TL_RANGE and TD_RANGE are displayed in hexadecimal notation.

[-pool {<pool_id> | <pool naming>} ]
Specifies the pool ID or the pool name of Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe when you want to display the range for each tiering level of Dynamic Tiering, Dynamic Tiering for Mainframe, active flash, or active flash for mainframe pools. When you specify only digits, it is recognized as a pool ID. When the pool name consists of digits, specify the pool ID instead of the pool name. This option is effective only when the -key option is specified.
[-pcap]
Supported storage systems:
  • VSP 5000 series
  • VSP G1x00 and VSP F1500
  • VSP G130, G/F350, G/F370, G/F700, G/F900

Specifies the actual capacity. This option is valid only when the -key opt option is specified. For the pool for which automatic addition settings of pool volumes whose accelerated compression is enabled are enabled, check the pool capacity by specifying this option.

If the microcode version does not support this option, nothing is displayed when this option is specified.

Example 1

Displaying the pool information of the pool for Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, and active flash for mainframe.

Description of each column in output example:

PID
Displays the pool ID of Dynamic Provisioning/Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, or active flash for mainframe.
POLS
Displays the status of the pool.
  • POLN: "Pool Normal" (The pool is in the normal status.)
  • POLF: "Pool Full" (The pool is in the overflow status exceeding the threshold.)
  • POLS: "Pool Suspend" (The pool is in the overflow status exceeding the threshold and is blocked.)
  • POLE: "Pool failure" (The pool is suspended in the failure status.) In this status, the pool information cannot be displayed.
U(%)
Displays the usage rate of the pool (including the mapped capacity and the capacity for Full Allocation).
AV_CAP(MB)
Displays the available capacity (megabytes) for the volumes of Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, or active flash for mainframe mapped to this pool.
TP_CAP(MB)
Displays the total capacity (megabytes) of the pool.
W(%)
Displays the threshold value for WARNING set for the pool.
H(%)
Displays the threshold value set for the pool as the high water mark.
Num
Displays the number of LDEVs composing the pool.
LDEV#
Displays the LDEV number of a pool-VOL that includes the pool management area. 65535(ffff) is displayed if the pool is being created.
LCNT
Displays the total number of Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, or active flash for mainframe volumes mapped to the pool.
TL_CAP(MB)
Displays the total capacity (megabytes) of all Dynamic Provisioning, Dynamic Provisioning for Mainframe, Dynamic Tiering, active flash, Dynamic Tiering for Mainframe, or active flash for mainframe virtual volumes and Thin Image pairs mapped to the pool.
BM
Displays the I/O Blocking Mode of the pool.
  • PF (Pool Full): If the pool is full, you cannot read from the target DP-VOL or write to the target DP-VOL. If the pool VOL is blocked, you can read from the target DP-VOL or write to the target DP-VOL.
  • PB (Pool vol Blockade): If the pool VOL is blocked, you cannot read from the target DP-VOL or write to the target DP-VOL. If the pool is full, you can read from the target DP-VOL or write to the target DP-VOL.
  • FB (Full or Blockade): You cannot read from the target DP-VOL or write to the target DP-VOL if the pool is full and/or pool VOL is blocked.
  • NB (No Blocking): You can read from the target DP-VOL or write to the target DP-VOL even if the pool is full or pool VOL is blocked.
  • - (Not supported): The configuration that does not support the I/O Blocking Mode.
TR_CAP(MB)
Shows the sum of the pool capacities (megabytes) which are reserved for the volumes on which Full Allocation or Proprietary Anchor is enabled. For a configuration that does not support Full Allocation, a hyphen (-) is displayed.
RCNT
Shows the number of volumes for which Full Allocation is enabled that are mapped to a pool. In the configuration that does not support Full Allocation, a hyphen (-) is displayed.

The following figures show the difference between the capacity ratio changing according to whether Full Allocation is enabled or disabled when DP-VOL is written. The "Mapped capacity" in the figure is the total capacity of the user data in each virtual volumes and the page capacity which is storing the control information.

MODE
Displays the execution mode.
  • DEF: The start/termination of the monitor is performed by the instruction of the CCI, and the Tier range setting is performed by the automatic calculation of the storage system.
  • AUT: The start/termination of the monitor is performed by time specification, and the Tier range setting is performed by the automatic calculation of the storage system.
    Note:

    AUT cannot be instructed from the CCI. AUT can only performed if displayed when set from the SN2.

STS
Displays the operational status of the performance monitor and the tier relocation.
  • STP: The performance monitor and the tier relocation are stopped.

DAT

Displays the status of the monitor information.

  • VAL: Valid.
  • INV: Invalid.
  • PND: Being calculated.
TNO

0 (0x00000000) to 4294967294 (0xFFFFFFFE)
When "all" is set to the level of tiering policy, the lowest limit value of the tier is displayed. When there is no V-VOL where "all" is set to the level of tiering policy, or when there is no V-VOL related to the pool, the invalid value "-" (0xFFFFFFFF) is displayed. If the -fix option is specified, this displays the value in parentheses given in hexadecimal.

When there is no V-VOL where "all" is set to the level of tiering policy, or when there is no V-VOL related to the pool, the invalid value "-" (0xFFFFFFFF) is displayed. If the -fix option is specified, this displays the value in parentheses given in hexadecimal.
