LDEV Status

Current status of the LDEV.

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).

Capacity

• Free: The free space capacity of which the LDEVs 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 LDEVs 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. Because LDEVs that are allocated in the virtual capacity area are displayed in this table, the capacity of which "Free" is deducted from "Total" might be larger than the total capacity of LDEVs in this table.

Drive Type/RPM

Drive type and rpm in use on this LDEV.

Interleaved Parity Groups

Interleaved (concatenated) parity groups.

Accelerated Compression

Displays information about the accelerated compression of the parity group that is created of LDEVs

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.

Copy-Back Mode

Displays the setting of the copy-back mode.

• Enable: Copy-back mode is enabled in the parity groups.
• Disable: Copy-back mode is disabled in the parity group

Number of LDEVs

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

LDEV ID

LDEV identifier, which is the combination of LDKC, CU, and LDEV.

LDEV Name

LDEV name.

Status

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.

Attribute

Attribute of the volume indicating how the LDEV is being used.

• Command Device: The volume is a command device.
• Remote Command Device: The volume is a remote command device.
• JNL VOL: The volume is a journal volume.
• Pool VOL: The volume is a pool volume. The number in the parenthesis indicates the pool identifier.
• Quorum Disk: Quorum disk for global-active device.
• Data Direct Mapping: LDEV of the data direct mapping attribute.
• Hyphen (-): Volume in which the attribute is not defined

Resource Group Name (ID)

Resource group name and identifier of the LDEV.

Expanded Space Used¹

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

This item displays whether the LDEV area is allocated in the expanded or physical area.

Yes: LDEV is allocated in the expanded area.

No: LDEV is allocated in the physical area.

Virtual Storage Machine¹

Information about the virtual storage machine.

• Model / Serial Number¹: Model name and serial number of the virtual storage machine that has LDEV.
• LDEV ID¹: Virtual LDEV ID. If a Virtual LDEV ID is not assigned to the LDEV, this column is blank.
• Device Name¹: Virtual device name, which is a combination of the virtual emulation type, virtual LUSE volume number, and the virtual CVS attribute. Values of the virtual emulation type, virtual LUSE volume number, and virtual CVS attribute appear only for items that have been set. This column is blank when the virtual emulation type, virtual LUSE volume number, and virtual CVS attribute are not set. If the virtual CVS attribute is set, CVS is attached as the suffix to the device name.
• SSID¹: Virtual SSID. If Virtual SSID is not set for LDEV, this column is blank.
• Attribute¹: Virtual LDEV attribute. If the attribute is not set for LDEV, this column is blank.
