Problem with HP_LTT

[Robert Ferro_1]

Hello

Hardware configuration
HP Ultrium-1 Surestore 215 External
Adaptec AIC-7892 Ultra 160/m SCSI host adapter

The Adaptec SCSI is the SCSI# 2 (i have 2 RAID controlers)

Software: Linux RedHat AS 2.1, the device /dev/sg10 was create and can be accessed by ARCServe V9. I stop the ARCServe Services and start hp_ltt and i got the error

OC_Exception_c caught: Internal error (oc_devicemap_linux.cpp,
534, Unable to find the sg device file)

Thanks you for your Help

Robert,

There is some helpful informationin the HP L&TT user Guide.

ftp://ftp.compaq.com/pub/products/storageworks/techdoc/ltt/5969-5752.pdf

Here is the section that may help you.

Why doesn't L&TT for Linux "see" some of my devices?
To detect a surrogate SCSI device, you must configure the modules.conf file for
the new device you have connected. After modifying this file, reboot the computer
so that the new device is recognized by the scsi/sg layer. Linux does not support
hot swapping of SCSI devices. To reconfigure the modules.conf file:

1. Login as root.
2. Edit the following file:
vi /etc/modules.conf
3. Add the following line as appropriate:
add options scsi_mod max_scsi_luns=128
4. Reboot the computer.

and

How do I connect/disconnect a SCSI device in Linux without rebooting?

â   To add a new device, connect the device and run the following command:
echo "scsi add-single-device
" >/proc/scsi/scsi
â   To remove a device, run the following command and disconnect the device.
echo "scsi remove-single-device
" >/proc/scsi/

Thanks you for your answer
I have already read the document and applied the modification to the /etc/modules.conf
Have hp_ltt an option to select the device?
