HP XP RAID Manager Software - Manual (Page 14)

Figure 1 Example of a RAID Manager configuration on z/Linux
The restrictions for using RAID Manager with z/Linux are:
•
Command device. RAID Manager uses a SCSI Path-through driver to access the command
device. As such, the command device must be connected through FCP adaptors.
•
Open Volumes via FCP. You can control the Business Copy and Continuous Access Synchronous
pair operations without any restrictions.
•
Mainframe (3390-9A) Volumes via FICON. You cannot control the volumes (3390-9A) that
are directly connected to FICON for Business Copy pair operations. Also, mainframe volumes
must be mapped to a CHF port to address target volumes using a command device, as shown
in
Figure 1 (page 14) . The mainframe volume does not have to be connected to an FCP
adaptor.
Business Copy supports only 3390-9A multiplatform volumes. Continuous Access Synchronous
does not support multiplatform volumes (including 3390-9A) via FICON.
•
Volume discovery via FICON. The inqraid command discovers the FCP volume information by
using SCSI inquiry. FICON volumes can be discovered only by using RAID Manager to convert
the mainframe interface (Read_device_characteristics or Read_configuration_data) to SCSI
Inquiry. As such, the information that is required to run the inqraid command cannot be
implemented, as shown in the following example:
sles8z:/HORCM/usr/bin# ls /dev/dasd* | ./inqraid
/dev/dasda -> [ST] Unknown Ser = 1920 LDEV = 4 [HTC ] [0704_3390_0A]
/dev/dasdaa -> [ST] Unknown Ser = 62724 LDEV =4120 [HTC ] [C018_3390_0A]
/dev/dasdab -> [ST] Unknown Ser = 62724 LDEV =4121 [HTC ] [C019_3390_0A]
sles8z:/HORCM/usr/bin# ls /dev/dasd* | ./inqraid -CLI
DEVICE_FILE PORT SERIAL LDEV CTG H/M/12 SSID R:Group PRODUCT_ID
dasda - 1920 4 - - 00C0 - 0704_3390_0A
dasdaa - 62724 4120 - - 9810 - C018_3390_0A
dasdab - 62724 4121 - - 9810 - C019_3390_0A
In the previous example, the Product_ID, C019_3390_0A, has the following associations:
•
C019 indicates the Devno
•
3390 indicates the Dev_type
•
0A indicates the Dev_model
