The cpqary3 driver 23 provides disk and SCSI tape support for the HP Smart Array controllers. 24 .LP 25 Please refer to the cpqary3 release notes, for the supported HP Smart Array 26 Controllers and Storage boxes. 27 .LP 28 Each controller should be the sole initiator on a SCSI bus. Auto 29 configuration code determines if the adapter is present at the Configured 30 address and what types of devices are attached to it. 31 .SH CONFIGURATION 32 Use the Array Configuration Utility to configure the controllers. Each 33 controller can support up to 32 logical volumes. In addition, each controller 34 supports up to a maximum of 28 connected SCSI tape drives. 35 With 1.90 and later versions of cpqary3 driver, HP Smart Array SAS controllers, 36 having Firmware Revision 5.10 or later, will support 64 logical drives. This 37 firmware also supports Dual Domian Multipath configurations. 38 .LP 39 The driver attempts to initialize itself in accordance with the information 40 found in the configuration file, /kernel/drv/cpqary3.conf. 41 .LP 42 New component - hmaeventd which logs the storage events onto console and to the 43 Integrated Management Log is made a part of HPQhma 5.0.0 package, which is not 44 part of the operating system. Therefore, by default, notify on event 45 functionality is disabled in the driver from 2.1.0 onwards. Storage event 46 logging may be enabled in the driver by modifying cpqary3.conf to set the 47 cpqary3_noe property to "on". Modification of driver properties requires 48 reloading the driver, which in most cases will occur only following a reboot of 49 the system. 50 .LP 51 The target driver's configuration file shall need entries if support is needed 52 for targets numbering greater than the default number of targets supported by 53 the corresponding target driver. 54 .LP 55 By default, entries for SCSI target numbers 0 to 15 are present in sd.conf. 56 Entries for target numbers 16 and above must be added to the \&'scsi' class in 57 sd.conf to support additional corresponding logical volumes. 58 .LP 59 If SCSI tape drives are connected to the supported controllers, entries for 60 target IDs from 33 to 33+N must be added in the /kernel/drv/st.conf file under 61 \&'scsi' class, where N is the total number of SCSI tape drives connected to the 62 controller with largest number of tape drives connected to it, in the existing 63 configuration. For example, two supported controller, c1 and c2 are present in 64 the system. If controller c1 has two (2) tape drives and controller c2 has five 65 (5) tape drives connected, then entries for target IDs 33 thru 38 are required 66 under 'scsi' class in /kernel/drv/st.conf file. The maximum number of tape 67 drives that can be connected to a controller is 28. With 1.90 and later versions 68 of cpqary3 driver, if tape drives are connected to Smart Array SAS controllers, 69 then target ID entries for tape drives from 65 to 65+N must be added in 70 /kernel/drv/st.conf file under the \&'scsi' class. 71 .SH FILES 72 .PD 0 73 .TP 25 74 .B /kernel/drv/cpqary3.conf 75 - configuration file for CPQary3 76 .PD 77 .SH "SEE ALSO" 78 .BR driver.conf (4), 79 .BR sd (7D), 80 .BR st (7D) 81 .LP 82 .SH NOTES 83 .LP 84 The Smart Array controllers supported by the current version of the 85 cpqary3 driver do not support 'format unit' SCSI command. Hence, selecting 86 \&'format' option under 'format' utility main menu is not supported. In addition, 87 the 'repair' option under 'format' utility main menu is not supported as this 88 operation is not applicable to Logical volumes connected to the supported Smart 89 Array controllers.
