For each hardware module on the system,
ioscan
displays by default the hardware path to the
hardware module, the class of the hardware module, and a brief description. If the device is
connected, but not found, then it is in a “no hardware” state. If the device is in a no hardware
state, use
sasmgr
to further check the state of the I/O card; see
“Displaying General Statistics
and Information” (page 57)
.
The sasmgr Utility
You can use the
sasmgr
utility to manage HP-UX Serial Attached SCSI (SAS) mass storage core
I/O controllers. The
sasmgr
command syntax is as follows:
SYNTAX
Path:
/opt/sas/bin
sasmgr [-h][-f] add -D device_file -q raid -q level=raid_level -q
enc_bay=enc:bay[,enc:bay] [-q size=size] [-q rebuild_rate=rate]
sasmgr [-h][-f] add -D device_file -q raid -q spare -q enc_bay=enc:bay
sasmgr [-h][-f] bdr -D device_file -q lun={all | lun_dsf}
