Parity Group Capacity

• Free: The free space capacity of which the internal (or external) volumes can be created is displayed. In a case for the free space of the accelerated compression-enabled parity group, this area displays the value of which the total mapped pages capacity of LDEVs (assigned in the physical area and external area) is deducted from the parity group capacity.The control information used by the storage system, such as control cylinders, is not included in the Free capacity.
• Total: The total capacity of the internal (or external) volumes and the free space is displayed. In a case for the total space of the accelerated compression-enabled parity group, this area displays the physical area capacity. The expanded capacity appears when existing parity groups with accelerated compression are enabled.

Number of Drives

• SSD: Displays the number of SSDs.
• SAS: Displays the number of SAS drives.
• Total: Displays the total number of drives.

Parity Group ID

The parity group identifiers of the parity groups in the storage system.

LDEV Status

The following icons are used to indicate the LDEV status:

• Normal: Normal status.
• Blocked: Host cannot access a blocked volume.
• Warning: Problem occurs in the volume.
• Formatting: Volume is being formatted.
• Preparing Quick Format: Volume is being prepared for quick formatting.
• Quick Formatting: Volume is being quick-formatted.
• Correction Access: Access attribute is being corrected.
• Copying: Data in the volume is being copied.
• Read Only: Data cannot be written on a read-only volume.
• Shredding: Volume is being shredded.
• Hyphen (-): Any status other than the above.

RAID Level

RAID level. An asterisk (*) indicates that the parity group to which the LDEV belongs is interleaved (concatenated). Either RAID level of the parity group is displayed.

Capacity

• Free: The free space capacity of which the internal volumes can be created is displayed. In a case for the free space of the accelerated compression-enabled parity group, this area displays the value of which the total mapped pages capacity of LDEVs (assigned in the physical area and external area) is deducted from the parity group capacity.The control information used by the storage system such as control cylinders is not included in the displayed capacity.
• Total: The total capacity of the internal volumes and the free space is displayed. In a case for the total space of the accelerated compression-enabled parity group, this area displays the physical area capacity. The expanded capacity appears when existing parity groups with accelerated compression is enabled.

Physical Capacity¹

Capacity assured for writing data in the parity group.

Number of LDEVs

• Unallocated: Number of unallocated LDEVs.
• Total: Total number of LDEVs.

Drive Type/RPM

Drive type and rpm in use on this LDEV.

Encryption

Encryption information:

• Enable: encrypted parity group
• Disable: non-encrypted parity group
• - (hyphen): parity group in which the encryption setting is not defined

Accelerated Compression¹

Displays the information about the accelerated compression of the parity group.

• Enabled: The accelerated compression of the parity group is enabled.
• Disabled: The accelerated compression of the parity group is disabled.
• - (hyphen): The parity group with the accelerated compression is not supported.

Expanded Space Used ¹

Displays whether the LDEV is allocated in the expanded area or the physical area. If accelerated compression is enabled, LDEVs are initially allocated in the physical area, and then LDEVs are allocated in the expanded area.

• Yes: LDEV is allocated in the expanded area.
• No: LDEV is allocated in the physical area.

Attribute

Displays the attribute of the parity group.

- (hyphen): parity group in which the attribute is not defined.

Copy-Back Mode

Displays the setting of the copy-back mode.

• Enable: Copy-back mode is set to parity groups.
• Disable: Copy-back mode is not set to parity groups.

Resource Group Name (ID)

Resource group name and ID of which this parity group is a member.

Virtual Storage Machine¹

Model type and serial number of the virtual storage machine to which the parity group belongs.
