If you cannot solve the problem on your own, contact your HP representative. NOTE: Before using these troubleshooting steps, you must have installed, configured, and verified the HP 8 Internal Port SAS Controller hardware and software on the host and on any devices. Troubleshooting sasd Troubleshooting sasd requires the use of the following two utilities: • ioscan • sasmgr The ioscan Utility By default, ioscan scans the system and lists all reportable hardware found. The types of hardware reported include processors, memory, interface cards and I/O devices. For HP-UX 11i v2, the ioscan command syntax is as follows: SYNTAX /usr/sbin/ioscan [-k|-u] [-e] [-d driver|-C class] [-I instance] [-H hw_path] [-f[-n ]|-F[-n]] [devfile] /usr/sbin/ioscan -M driver -H hw_path [-I instance] /usr/sbin/ioscan -t For HP-UX 11i v3, the ioscan command syntax is as follows: SYNTAX /usr/sbin/ioscan [-N] [-k|-u] [-e] [-d driver | -C class] [-I instance] [-H hw_path] [ -f[-n] | -F[-n] ] [devfile] /usr/sbin/ioscan [-b] -M driver -H hw_path [-I instance] /usr/sbin/ioscan -t /usr/sbin/ioscan -P property [-d driver | -C class] [-I instance] [-H hw_path] [devfile] /usr/sbin/ioscan -m lun [-F] [-d driver | -C class] [-I instance] [-H lun hw_path] [devfile] Introduction 51

4 Configuring and Troubleshooting the Controller Online
This chapter describes the online configuration, troubleshooting, and maintenance tools for HP
internal SAS controllers. This chapter includes the following topics:
“Introduction” (page 51)
“Troubleshooting sasd” (page 51)
“The sasmgr Command Set” (page 54)
“Using sasmgr: Common Command Examples” (page 57)

Introduction
A systematic approach to troubleshooting helps isolate the problem. If you cannot solve the
problem on your own, contact your HP representative.
NOTE:
Before using these troubleshooting steps, you must have installed, configured, and
verified the HP 8 Internal Port SAS Controller hardware and software on the host and on any
devices.
Troubleshooting sasd
Troubleshooting
sasd
requires the use of the following two utilities:
•
ioscan
•
sasmgr
The ioscan Utility
By default,
ioscan
scans the system and lists all reportable hardware found. The types of
hardware reported include processors, memory, interface cards and I/O devices. For HP-UX 11i
v2, the
ioscan
command syntax is as follows:
SYNTAX
/usr/sbin/ioscan [-k|-u] [-e] [-d driver|-C class] [-I instance]
[-H hw_path] [-f[-n ]|-F[-n]] [devfile]
/usr/sbin/ioscan -M driver -H hw_path [-I instance]
/usr/sbin/ioscan -t
For HP-UX 11i v3, the
ioscan
command syntax is as follows:
SYNTAX
/usr/sbin/ioscan [-N] [-k|-u] [-e] [-d driver | -C class] [-I instance]
[-H hw_path] [ -f[-n] | -F[-n] ] [devfile]
/usr/sbin/ioscan [-b] -M driver -H hw_path [-I instance]
/usr/sbin/ioscan -t
/usr/sbin/ioscan -P property [-d driver | -C class] [-I instance]
[-H hw_path] [devfile]
/usr/sbin/ioscan -m lun [-F] [-d driver | -C class] [-I instance]
[-H lun hw_path] [devfile]
