显示全部When configuring a DS8000 storage image for attached Open Systems host systems, you need to
perform the following basic steps, using either the DS8000 Storage Manager or the DS CLI:
1. Prepare the available physical storage capacity.
(a) Create arrays from array sites (8 DDMs) by specifying the RAID level (RAID-5 or RAID-
10)
(b) Create ranks from the arrays by specifying the storage type (FB or CKD)
Fixed block (FB): used for Open Systems hosts and System i hosts
Count key data (CKD): used for System z hosts
(c) Create extent pools populated with ranks to provide the logical storage capacity from
which the volumes for the individual host systems will be created.
2. Configure the DS8000 subsystem's I/O ports by setting the Fibre Channel topology for the
available host adapter FC ports that are used for the host attachments.
(a) FC-AL: The FC-AL topology setting enables the SCSI ULP (upper layer protocol) with a
FC-AL topology.
(b) SCSI-FCP: The SCSI-FCP topology setting enables the SCSI ULP with a point-to-point or
switched fabric topology. PPRC path I/O operations can only be enabled using this
setting.
(c) FICON: The FICON topology setting enables the FICON ULP with a point-to-point or
switched fabric topology.
3. Create volumes for the attached open systems host systems (FB volumes).
(a) Create FB volumes from extents of a given extent pool.
(b) Create volume groups to group volumes for a common assignment to a host system.
(c) Create host connections by specifying the WWPNs of the attached host system ports.
(d) Finally assign the volume groups to host connections to enable I/O access.
