.
For windows systems this is a common problem. 
Try to upgrade the firmware of the SAN switches and the firmware of the
fibre cards. Also upgrade the driver of the card or st patches for Solaris.

Can you tell us the model of the library you have and if the drives are
fiber or scsi. And if scsi, the model of the scsi2fibre router

Subject: [Veritas-bu] How to get SSO SAN Media Server LTO Drives
back*without* rebooting ?

Hi all,

We are consistently having to reboot our servers (both windows and unix) to
get
our LTO3 SSO drives back (after they mysteriously disappear).

Scenario:

For one reason or another we loose a drive and to get it back for example we
powercycle our library and our NB master can now see the drive(s), however,
our
SAN Media servers cannot see the drives unless we reboot them. This is *bad*
-
_really_ bad. These are production servers and cannot be rebooted on a whim.

So the question:
=-=-=-=-=-=-=-=

Can anyone recommend how to get SAN Media Servers to see their SSO drives
again
*without* having to reboot ?

We are running NB-6.0-MP3 both Solaris and Windows 2003 Masters.

Regards

 -aW
