15 15 .SH NAME
16 -.LP
17 16 cpqary3 - provides disk and SCSI tape support for HP Smart Array controllers
18 -.LP
19 17 .SH DESCRIPTION
20 18 .LP
21 19 The cpqary3 module provides low-level interface routines between the common
22 20 disk I/O subsystem and the HP SMART Array controllers. The cpqary3 driver
23 21 provides disk and SCSI tape support for the HP Smart Array controllers.
24 22 .LP
25 23 Please refer to the cpqary3 release notes, for the supported HP Smart Array
26 24 Controllers and Storage boxes.
27 25 .LP
28 26 Each controller should be the sole initiator on a SCSI bus. Auto
29 27 configuration code determines if the adapter is present at the Configured
30 28 address and what types of devices are attached to it.
31 29 .SH CONFIGURATION
32 30 Use the Array Configuration Utility to configure the controllers. Each
33 31 controller can support up to 32 logical volumes. In addition, each controller
34 32 supports up to a maximum of 28 connected SCSI tape drives.
35 33 With 1.90 and later versions of cpqary3 driver, HP Smart Array SAS controllers,
36 34 having Firmware Revision 5.10 or later, will support 64 logical drives. This
37 35 firmware also supports Dual Domian Multipath configurations.
38 36 .LP
39 37 The driver attempts to initialize itself in accordance with the information
40 38 found in the configuration file, /kernel/drv/cpqary3.conf.
41 39 .LP
42 40 New component - hmaeventd which logs the storage events onto console and to the
43 41 Integrated Management Log is made a part of HPQhma 5.0.0 package, which is not
44 42 part of the operating system. Therefore, by default, notify on event
45 43 functionality is disabled in the driver from 2.1.0 onwards. Storage event
46 44 logging may be enabled in the driver by modifying cpqary3.conf to set the
47 45 cpqary3_noe property to "on". Modification of driver properties requires
48 46 reloading the driver, which in most cases will occur only following a reboot of
49 47 the system.
50 48 .LP
51 49 The target driver's configuration file shall need entries if support is needed
52 50 for targets numbering greater than the default number of targets supported by
53 51 the corresponding target driver.
54 52 .LP
55 53 By default, entries for SCSI target numbers 0 to 15 are present in sd.conf.
56 54 Entries for target numbers 16 and above must be added to the \&'scsi' class in
57 55 sd.conf to support additional corresponding logical volumes.
58 56 .LP
59 57 If SCSI tape drives are connected to the supported controllers, entries for
60 58 target IDs from 33 to 33+N must be added in the /kernel/drv/st.conf file under
61 59 \&'scsi' class, where N is the total number of SCSI tape drives connected to the
62 60 controller with largest number of tape drives connected to it, in the existing
63 61 configuration. For example, two supported controller, c1 and c2 are present in
64 62 the system. If controller c1 has two (2) tape drives and controller c2 has five
65 63 (5) tape drives connected, then entries for target IDs 33 thru 38 are required
66 64 under 'scsi' class in /kernel/drv/st.conf file. The maximum number of tape
67 65 drives that can be connected to a controller is 28. With 1.90 and later versions
68 66 of cpqary3 driver, if tape drives are connected to Smart Array SAS controllers,
69 67 then target ID entries for tape drives from 65 to 65+N must be added in
70 68 /kernel/drv/st.conf file under the \&'scsi' class.

83 80 .LP
84 81 The Smart Array controllers supported by the current version of the
85 82 cpqary3 driver do not support 'format unit' SCSI command. Hence, selecting
86 83 \&'format' option under 'format' utility main menu is not supported. In addition,
87 84 the 'repair' option under 'format' utility main menu is not supported as this
88 85 operation is not applicable to Logical volumes connected to the supported Smart
89 86 Array controllers.
