Configuring kernel SCSI parameters on a Tru64 UNIX host Complete this task to set up and configure the Hewlett-Packard AlphaServer Tru64 UNIX device parameter database. About this task This procedure applies to all versions of Tru64 UNIX 4.0f and later. See the Tru64 UNIX man files for ddr.dbase and ddr_config for more information. Procedure With the storage quiesced, the host system in single-user mode, and logged in to the host system with root privileges, edit the /etc/ddr.dbase file, and include the following parameter values in the DISKS subsection. Table 1 provides the recommended settings for the DS8000® SCSI device. Table 1. Recommended Tru64 UNIX settings for the SCSI DEVICE. Parameters Recommended settings TypeSubClass hard_disk, raid BadBlockRecovery disabled DynamicGeometry true LongTimeoutRetry enabled TagQueueDepth 20 ReadyTimeSeconds 180 CMD_Write_Verify supported InquiryLength 255 RequestSenseLength 255 Compile by executing the following command: ddr_config -c . Confirm that the values were included by issuing the following command: ddr_config -s disk IBM 2107 . Edit the /sys/data/cam_data.c. file to change the nonread/write command timeout values in the changeable disk driver timeout section from 10 seconds to 60. Locate the existing timeout value u_long cdisk_to_def = 10; /10* seconds */ , and change the value to u_long cdisk_to_def = 60; /60* seconds */ cdisk_to_def = 60; /60* seconds */
