• SLU IDThe P-VOL’s SLU ID. If the SLU attribute is not specified for the P-VOL, a hyphen (-) is displayed.
• Port IDThe port name of the P-VOL LDEV's LUN path. If the path is not defined, a blank is displayed.
• Host Group Name / iSCSI Target AliasThe host group name and ID or iSCSI target alias and ID of the P-VOL LDEV's LUN path. If the path is not defined, a blank is displayed.
• iSCSI Target NameThe P-VOL's iSCSI target name. If the LUN path is not defined, a blank is displayed.

  • ExternalExternal volume
• Attribute(VSP Gx00 models and VSP Fx00 models only) The P-VOL's attribute.
• CapacityThe P-VOL's capacity.
• CLPRThe P-VOL's CLPR ID.
• EncryptionThe P-VOL's encryption information.
  • EnabledEncryption is enabled for the parity group to which the P-VOL's LDEV belongs, or the P-VOL is a V-VOL associated with a pool in which a pool volume has encryption enabled.
  • DisabledEncryption is disabled for the parity group to which the P-VOL's LDEV belongs, or the P-VOL is a V-VOL associated with a pool in which a pool volume has encryption disabled.
  • MixedThe pool to which the P-VOL's LDEV belongs contains two or more of the following:
    • Volume for which encryption is enabled
    • Volume for which encryption is disabled
    • External volume

  Note: Data encryption is not ensured in an LDEV with Mixed encryption status. If you want to manage data encryption, use LDEVs with the Enabled or Disabled status.

  If the LDEV is an external volume or migration volume, a hyphen (-) is displayed.

  For DP-VOLs, the pool to which an LDEV belongs is an external volume or blocked.

• Capacity Saving Information about the P-VOL's capacity saving function.

• Virtual LDEV IDThe identification number of the P-VOL’s virtual LDEV.
• Virtual Device NameThe name of the P-VOL’s virtual device, in a combined format of "virtual emulation type", "number of virtual LUSE volumes", and "virtual CVS attribute". Each of these three items is displayed only if it is specified. If none of them are specified, a blank is displayed.
• Virtual SSIDThe virtual SSID of the P-VOL. If no virtual SSID is specified, a blank is displayed.

  • Enabled Encryption is enabled for the parity group to which S-VOL's LDEV belongs, or the P-VOL is a V-VOL associated with a pool in which a pool volume has encryption enabled.
  • Disabled Encryption is disabled for the parity group to which S-VOL's LDEV belongs, or the P-VOL is a V-VOL associated with a pool in which a pool volume has encryption disabled.
  • MixedThe pool to which S-VOL's LDEV belongs contains two or more of the following:
    • Volume for which encryption is enabled
    • Volume for which encryption is disabled
    • External volume

    Note: Data encryption is not ensured in an LDEV with Mixed encryption status. If you want to manage data encryption, use LDEVs with the Enabled or Disabled status.

  • If the LDEV is an external volume or migration volume, a hyphen (-) is displayed.
