list diskgroup lsarraysite, showarraysite Like the 2105 disk group, a 2107/242x or 1750 array site consists of eight storage devices that are made into a RAID array. The 2107/242x does not support the JBOD array configuration.
list port lsioport, showioport

Like 2105, the 2107/242x supports Fibre Channel and ESCON ports. The 2107/242x does not support parallel SCSI ports. The 1750 does not support ESCON ports.

The maximum quantity of host device adapter cards and I/O ports depends on 2107/242x model number and on the quantity of installed I/O enclosure features.

The 2107/242x CLI lsioport and showioport commands include the -metrics parameter that returns the performance counter values for the respective I/O port IDs. The -metrics parameter provides the means to monitor I/O port performance statistics.

For the 2107/242x, an I/O adapter card is assigned to a storage image.

For the 1750, the I/O adapter is integrated with the RAID controller.

Note 1: Volume space configuration is a primary difference between the 2105 and the 2107/242x. For the 2105, one command configures an array site into a RAID array and rank. For the 2107/242x, one command configures an array site into an array, and a second command configures an array into a rank. For the 2105, a rank is configured as fixed block or CKD, and a CKD rank can contain “interleave” CKD volumes. For the 2107/242x, a rank is assigned to a user-defined extent pool object, which the user defines as either the fixed block or CKD storage type. The “interleave” volume construct does not exist for the 2107/242x. For the 2105, a volume is configured from a specific rank, and cannot span rank boundaries. For the 2107/242x, a volume is configured from an extent pool. An extent pool can contain multiple ranks. A 2107/242x volume consists of one or more extents that can be allocated from one or more ranks. The fixed block extent size is 1 GiB, where 1 GiB = 1,073,741,824 (2^30 bytes).Each block contains 512 bytes of usable data space. A CKD extent is 0.94 GiB or 1113 CKD cylinders.

For the 2105, a rank is either assigned to server 0 or server 1, dependent on array site location. A 2105 rank is assigned to one of four possible LSS IDs, dependent on device adapter pair location and storage type configuration.

For the 2107/242x, an extent pool is assigned to server 0 or server 1. A rank that is configured from any array site can be assigned to a server 0 or 1 extent pool. Array site position and device adapter pairs are not factors for the rank-to-extent-pool assignment. A volume that is created from a server 0 extent pool is assigned to an even-numbered LSS ID. A volume created from a server 1 extent pool is assigned to odd-numbered LSS ID. A user must define at least two extent pools (0 and 1) but can define as many extent pools as there are ranks. For 2105, a user can delete a rank but cannot delete a volume. For the 2107/242x, a user can delete a single volume, rank, or extent pool. The 2107/242x CLI showrank and showextpool commands include a -metrics parameter that returns the performance counter values for a specified rank or extent pool ID. The -metrics parameter provides the means to monitor rank and extent pool performance statistics.
Note 2: A 2107/242x ESCON I/O port is used for z Systems™ host attachment but cannot be configured as a remote mirror and copy path. Each ESCON I/O port must be assigned to only one address group. An address group is a set of 16 LSS IDs that are configured as CKD LCUs; for example, 0x00 to 0x0F. ESCON I/O port access to 2107/242x CKD volumes is constrained to the address group LCU volumes, up to 4096 volumes.

A 2107/242x Fibre Channel port is configured for either SCSI-FCP or FICON® protocol. Like 2105, a FICON port is restricted to the point-to-point/switched fabric topology setting. A FICON I/O port is used for z Systems host attachment, but cannot be configured as a remote mirror and copy path. A FICON port must be configured for “anonymous” access mode, meaning that any z Systems host system port (WWNN or WWPN) has unrestricted access to all CKD volumes, up to 64 KB volumes.

Like the 2105, a 2107/242x Fibre Channel SCSI-FCP I/O port can be configured for either the point-to-point/switched fabric or FC-AL connection topologies. A port that uses the point-to-point/switched fabric topology can be simultaneously used for OS host system I/O and for remote mirror and copy path configurations. Like 2105, a 2107/242x Fibre Channel SCSI-FCP I/O port allows only “identified” host system ports to access volumes. A host system port WWPN must be identified (registered) to each I/O port through which volume access is intended. For the 2107/242x, this configuration constraint is defined as I/O port “identified” access mode. Host system port WWPN identification is accomplished by the CLI mkhostconnect command.
Note 3: A 2107/242x storage image can contain up to 32 000 volumes, whereas a 2105 unit can contain up to 8 000 volumes. Otherwise, the 2105 and 2107/242x volume definitions and characteristics are identical.

For 2107/242x CKD PAV volumes, the CLI list and show commands identify both the original base and current base volume assignments. The original and current base concept exists for 2105, but specific relationships are not identified in the output.

The 2107/242x CLI provides a specific set of volume commands for each storage type (fixed block or CKD) as a means to clarify input parameter and output device adapter definitions.

The 2107/242x CLI showfbvol and showckdvol commands include a -metrics parameter that returns the performance counter values for a specified volume ID. The -metrics parameter provides the means to monitor volume performance statistics.
Note 4: The 2105 volume access commands concern volume ID assignment to a SCSI-FCP host port initiator or WWPN. For the 2107/242x, volume IDs are assigned to a user-defined volume group ID (mkvolgrp and chvolgrp). A volume group ID is then assigned to one or more host system ports (mkhostconnect and chhostconnect) as a means to complete the volume access configuration.

The volume group construct also exists in the 2105 internal code, but the construct is not externalized by the 2105 Specialist or CLI commands.

For the 2107/242x, a user must create a FICON/ESCON-all type volume group. This volume group ID is assigned to each ESCON I/O port and to each FICON I/O port. The volume group ID enables FICON access all storage image CKD volumes, up to 64 KB volumes. The volume group ID enables an ESCON I/O port to access to the storage image CKD Address Group volumes, up to 4 KB volumes.

For the 2107/242x fixed block volumes, a volume group must be configured as either "SCSI-mask" or "SCSI-map-256", depending whether the volume group is accessed by a SCSI-FCP host port that uses the report LUNs or poll LUNs access method protocol.
