IBM Array Detail Version 10.1.01

Detail reports are related to a specific enterprise object, such as a backup job or SAN fabric. You can only access detail reports through a link presented in the context of a main report, providing additional information that augments the main report. Detail reports cannot be generated, customized, or saved, as they are specific to the report from which they were derived. They are not available in search results.

Explore your data center using APTARE StorageConsole customizable report templates or by using parts of your IT infrastructure as entry points. Use Search to find reports, templates and dashboards across the portal.

Use the Reports tab to examine the APTARE StorageConsole catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. The main report is located here:

• Capacity values for IBM arrays may appear different from what is reported by the IBM CLI or IBM Tools, as IBM uses a decimal gigabyte—10^9 bytes, while StorageConsole uses 1024 for a KB when converting to GB.

Storage Unit	The Storage Unit ID contains the manufacturer, machine type, and serial number.
Storage Image	The Storage Image ID contains the manufacturer, machine type, and serial number.
Model	The storage unit model.
State	State of the storage unit: online, offline, resuming, quiescing, quiesce exception, forced quiescing, fenced, discovery.
Product	Storage Unit vendor.
# FC Ports	The # of Fibre Channel ports links to the Array Port Utilization report. Note that the # of FC ports may not match the number of rows shown in the drilldown report, as the Port Utilization report lists all the hosts connected to each port.
# Disks	Number of disks for this storage unit
Array Site Used	Amount of array storage used by the Array Site
# of Hosts	Number of hosts mapped to this array. Links to the Host Capacity & Utilization
Host Usage	Amount of capacity used by hosts

Capacity	Total raw or physical capacity. For IBM Arrays: Total array capacity derived from the physical DDMs (disk drive modules); specifically, the DDM usage in the array site
Allocated	Allocated storage is physical storage consumed, including parity overhead and system overhead. A gap between raw and allocated capacity may indicate unused capacity, such as drives in a rack that are not in use. For IBM Arrays: Amount of capacity that has been allocated is derived from DDM usage for array members and spares
Available	Total raw capacity of the array that has not been allocated. The size is displayed in the units you selected with the Advanced option when you generated the report. For IBM Arrays: Amount of capacity that is free, derived from unassigned and unconfigured DDMs
Raw Capacity Usage	Mouse over the thermometer to view the usage percentage

# of Array Sites	The number of array sites to which this array belongs. Links to the IBM Array Site Summary
Array Site Capacity	Sum of the capacity of all the associated array sites, derived from the capacity of the disks in each array site
Array Site Used	Sum of the array site capacity that is in used—that is, “assigned” to an array
Array Site Available	Array Site storage that has not been allocated—that is, “unassigned” to an array
Array Site Usage	Mouse over the thermometer to view the usage percentage

# of Arrays	Links to the IBM Array Summary
Array Capacity	The capacity of the Array (also known as the RAID Array)—one or more Array Sites can comprise an array and the capacity shown is the total for all the Array Sites in the array. This is raw array capacity.
Array Used	If an array is assigned to a rank, it is “used”
Array Available	Array capacity that is not part of a rank is “available”
Array Usage	Mouse over the thermometer to view the usage percentage.

# of Ranks	The number of ranks links to the IBM Rank Summary
Total Capacity	Sum of the capacity of all ranks
Used Capacity	Capacity assigned to an extent pool
Available Capacity	Capacity not assigned to an extent pool
Rank Usage	Mouse over the thermometer to view the percentage of the ranks that have been allocated.

# of Extent Pools	Links to the IBM Extent Pool Summary; both FB and CKD are included in this number.
FB Extent Pool Capacity	The sum of the capacity of all the fixed block extents in the extent pool; For FB, an extent is 1 GB.
FB Extent Pool Used	The amount of fixed block extent pool storage in assigned to a logical volume
FB Extent Pool Available	The fixed block extent pool storage that is not assigned to a logical volume
FB Extent Pool Usage	Mouse over the thermometer to view the percentage of the fixed block extent pool that is allocated.
CKD Extent Pool Capacity	The sum of the capacity of all the CKD extents in the extent pool; For CKD, an extent is 1 cylinder (.92 GB).
CKD Extent Pool Used	The amount of the CKD extent pool storage assigned to a logical volume.
CKD Extent Pool Available	The CKD extent pool storage that is not assigned to a logical volume.
CKD Extent Pool Usage	Mouse over the thermometer to view the percentage of the CKD extent pool that is allocated.

# of FB Volumes	Links to the LUN Utilization Summary.
Total FB Capacity	Sum of the capacity of all the fixed block volumes for this array.
# of Allocated FB	Links to the LUN Utilization Summary showing a list of allocated LUNs.
FB Allocated Capacity	Sum of all the fixed block volume capacity that has been allocated.
# of Unallocated FB	The number of unallocated fixed block volumes.
FB Unallocated Capacity	The fixed block capacity that is not in allocated.
# of CKD	Number of CKD volumes.
CKD Capacity	Sum of the capacity of all the CKD volumes for this array.

Name	Rank name links to the IBM Rank Summary.
Usage	Used Extents in the Rank.
Total Extents	Total Extents in the Rank.
Available	Extents in this Rank that are available for allocation in the Extent Pools; If the available amount equals the total amount, it indicates that the rank is not allocated to any Extent Pools.

Either 1 or 2 Ranks can comprise an Extent Pool. When it is a 1-to-1 relationship, the Extent Pool capacity values will look identical to the Rank values. Otherwise, they will be double the Rank values. All Ranks in an Extent Pool are of the same RAID type.

Name	Extent Pool name links to the IBM Extent Pool Summary.
Usage	Amount of Extent capacity that is in use.
Total Extents	Total Extent capacity.
Available	Available Extent capacity.
