9.1.2 Fibre Channel disks (RAID systems)

Two different disk types can be created on the Fibre Channel disks (for the usage scenarios
see section "Rules of usage for disks D3435 and D3475-8F" on page
are:
– a D3435 disk or
– a D3475-8F disk
If type D3475-8F is chosen the disk could be partitioned, but it should not partitioned if
MirrorView/SnapView in FibreCat or SRDF and TimeFinder in Symmetrix (contained in
Symmetrix host component = SHC-OSD) is to be used later because in this case the
smallest administrative unit is an LUN (logical unit = 1 logical disk). The required disk sizes
should always be set with RAID resources. One LUN should always correspond to one
BS2000 disk.
Configuration:
If the tab BS2 disks (Mconf) is selected, all possible BS2000 disks are listed on it. The
following actions are proposed: partition and/or import. You can now import and configure or
partition and configure the disk:
1. import and configure
In the case of import and configure the data on the disk remain unchanged and the
volume(s) is/are made available to BS2000. To obtain an overview of what will be
configured, press the button "Preview"; nothing else will be done. An interrupt is still
possible if this configuration is not required.
2. partition and configure
In the case of partition and configure the disk type is freely selectable and you can select
either disk type (D3435 or D3475-8F). The number of BS2000 disks on an LUN can also
be specified from 1 to 7 in the case of D3475-8F. Only slices of the same size can be
generated. In the case of partitioning, the disk is always overwritten. There is always
only 1 slice for disk type 3435.
After the configuration "none" appears in the column possible actions.

BS2000 disks: Configuration and BS2000 installation
The LUN has now been divided into 1 - 7 BS2000 disks of the same size.
All disks have the same format: KEY, NK2 or NK4. These BS2000 disks can
be initialized with Volumes+Pubsets. Points 5 - 8, with the explanations from

disks.
One D3435 disk per LUN has been configured. The format and the initial-
ization of the disk can only be written from BS2000 via SIR and/or VOLIN.
Volumes+Pubsets are not therefore available for the D3435 disks.
