LTO replacement

UNIX Solaris
1

Hi guys,

I've changed the LTO3 device, but the OS (Solaris10) doesn't feel it.
From the ok> prompt i've launched the probe-scsi-all command and it worked fine because i could see the new device; the from the ok> i booted the system (normal boot, probably a boot -r could be better..) and from the OS tried davfsadm and drvcfg, but nothing good. In the /dev/rmt/0 folder

ls -l /dev/rmt/0
lrwxrwxrwx 1 root other 44 Nov 19 2009 /dev/rmt/0 -> ../../devices/pci@1c,600000/scsi@2,1/st@4,0:

which is the old link and it does not work because there in no st@4,0 device , in /devices.

How can I upgrade the link? Should I manually remove the old links?

Thx4help

Did you try

devfsadm -C

?

...already tried... the /dev/rmt has been removed, but when I launch the devfsadm -c tape or devfsadm or drvcfg nothing change...

What does this command show:

cfgadm -al

Today we've tried the reboot -r also...but still the same problem..:confused::eek::confused:

Hello

Have you checked you can see the device from the ok prompt?
Would suggest you do a probe-scsi-all from there to check the system can see the LTO device.

Just a thought as Solaris might actually be fine

Best of luck.

Which release of Solaris 10? Your release may not support LTO3.

Hi guys,

I replaced the LTO drive once again and now it works properly; probably the first time the SUN technician had a faulted LTO drive..unbelievable!!!
