I've seen no response to this I think?

What a shame you didn't wait for SRSS 4.0 and use Solaris 10 with Trusted
Extensions :-(. We had to drop support for TSol8 in this release - too many
platforms.
Issues with the sunrays connecting to servers following reboots has me
questioning my configuration. I also question the uninstall/install of
the SW... /etc/opt/SUNWut and /var/opt/SUNWut are left behind... what
else isn't cleaned up properly?
The only other directory we use is /tmp/SUNWut but since that's tmpfs
there should be no problem. Many of the files in /etc/opt/SUNWut are
editable and as such are not cleaned up during package removal. The
files in /var/opt/SUNWut are dynamic and thus don't belong to any
package either. These directories can be safely removed manually
after uninstallation, and it's a fair cop that we ought to clean them
out from utinstall I think.
Config questions:
1: When setting up the utadm -a <NIC>, does it matter if I have an
"auth server list" ?
Not really.
I have been operating without. If I should be using 1,
would I list only other 4 servers, or all 5 ?
I'm assuming you're referring to this dialog:
Accept as is? ([Y]/N): n
new netmask: [255.255.255.0]
Do you want to offer IP addresses for this subnet? (Y/[N]):
auth server list: 172.16.0.29
To read auth server list from file, enter file name:
Auth server IP address (enter <CR> to end list):
I always enter all the addresses I'm interested in here, including
the one it already lists. You're building the AltAuth list here,
which takes precedence over AuthSrvr, which was the previous
value. They are not merged.
That said, this isn't critical if you have so many servers, since
you just need to enter enough addresses to meet your HA needs.
The entire group will load balance as appropriate when the
session is created. I'd be sure to use the NSCM policy so that
non-card sessions get load balanced upon login, if you allow
pseudo sessions at all.
2: I use the default DHCP lease time ( 24 hr. on solaris ) Is this
good, bad, or indifferent?
That's the default I believe. I've not heard any issues regarding this.

Bob
