How to scan a new SCSI device

[B. Jen]

We have added a new SCSI device(LTO2 tape drive) to the SCSI chain. How can we make the system to recognize the device?

Thank you.

Hi,

ioscan will recognize the newly added device.

Its good to have a copy of old ioscan if you've a long listing of devices.


run : insf -e
ioscan -fnC tape > /tmp/ioscan.out
diff
New device should list in the `diff` output.

Thanks,

Hi,

first look at kernel drivers from sam if there is something like stape. if not, add it.

then do:

# ioscan -fnC tape
# insf -e

Hi Jen,

ioscan is the universal UNIX command for scanning H/W. For checking a new SCSI device like LTO 2 tape drive, just execute the following commands:

# ioscan -fnC tape
# insf -e

Apparently, we don't live in the same UNIX
universe.

ra# man ioscan
No manual entry for ioscan.
ra# type ioscan
-bash: type: ioscan: not found
ra# find / -name ioscan
ra# uname -a
SunOS ra 5.10 Generic_137137-09 sun4u sparc SUNW,UltraSPARC-IIi-cEngine

"man devfsadm" would be more useful in that
part of the UNIX universe.

Hello B.Jen,
once you connect this drive with server and boot up server,

on command prompt you should type this, if everying is ok then you should able to get full hardware path with this command.

ioscan -fnC tape
insf -e


here is output for ioscan -fnC floppy in one of my old server,
