Jean-Louis,

Yes, I did find some information on a run time mechanism to
increase the 256 file limit (file limit stored in unsigned character).

The work-around employes requires the exection of /usr/lib/extendedFILE.so.1
prior to the binary being executed.

Following up on your maxcheck and Spindle number, I wonder if I 
couldn't automatically build an alternate disklist file with 
spindle number and swap it in and out. It would have to be done
dynamically (since my disklist changes and making changes in 
multiple locations is error prone), but that can be scripted and
called from cron.

/* I need something that will handle both formats of DLE
 *
finsen  /export2 zfs-snapshot2
finsen  /export/home-AZ /export/home   {
        user-tar2
        include "./[A-Z]*"
        }
 *
 */

Since this is an amanda-client issue, rather than an amanda server
issue, I need to ask you, how to execute this on the client-side
before attempting to check the DLE list. Is there a way to invoke
this from the amanda daemon?

 - Alternatively, if someone better versed than I am on the Solaris
   inetd or in SMF knows how to insert the requisit command on the
   client side - I would be appreciative if they would share their
   information.

                                                thank you,

                                                Brian
