HP StorageWorks XP Disk Array Mainframe Host Attachment and Operations Guide XP24000, XP20000 (A5951 - 96151, September 2007)

IMPORTANT:
ESCON interfaces support 1024 unit addresses per channel and up to 4096 devices for each set of 16
CU images using CUADD=0 through CUADD=F in the CNTLUNIT statement. ESCON channel interfaces
can be assigned to access individual groups of 16 control unit images.
The following example shows a sample IOCP definition for a storage system configured with:
• 2105 ID
• Four FICON channel paths. Two channels paths are connected to a FICON switch. Two channel
paths are directly connected to the storage system.
• Six control unit images (00, 01, 02, 03, 04, 05) with 256 LVIs per control unit
• 64 base addresses and 128 alias addresses per CU 00, 01, 02, and 03
• 128 base addresses and 128 alias addresses per CU 04 and 05

NOTE:
FICON channel interfaces support a maximum of 16,384 device addresses. Multiple groups of FICON
channels may be used to access the maximum of 65,280 devices that can be configured using a maximum
of 255 control unit images (CUADD 00 to FE).
