I think it depends on the size of the environment.

When I worked at a .edu (< 20 servers, 150 - 200 workstations, 5000
users) the unix admins were responsible for application installation
and maintenance as well.  As machines got big enough that we didn't
have to do silly tricks with OS components on multiple disks or on a
network file system (NFS or AFS) and administration practices improved
(jumpstart, distributed management mechanisms) the balance of time
shifted more toward application maintenance.  It wasn't that there was
more app work, there were fewer students helping out as admins.  The
last couple years there I found myself dealing more with security
issues due to the openness of the university (firewalls and disabling
telnet would stifle creativity).  I had to do really stupid stuff like
use the twist operation in tcpd to have a perl script connect to the
source of the incoming telnet connection to see if it was a wingate
telnet proxy and if so assume it was somebody that was just about to
install bitchx.

Re: UnionFS for Solaris

This sounds like these things could be accomplished with zones and lofs.

Also tools like either ops center or something like cfengine could help 
keep consistent files across multiple servers

and provide some basic configs, which would be common for several servers. The other decision (apart
unionfs) we investigating now is something like fsvs, but there is no OpenSolaris  package for it, and it is
quite annoying. However storing configs in svn is a good idea, but using custom fsvs soft  (to store
metadata changes - e.g. permission) is not very attractive for me.

Sun Grid Engine on OpenSolaris

Hello, 
I'm looking to install SGE on OpenSolaris entirely contained on EC2 and am wondering if SGE supports
OpenSolaris as a cluster operating system?
The most specific documentation I came across (http://www.sun.com/software/sge/techspec.xml) seems
to indicate OpenSolaris can be used only as an execution host but not as a master host. Is this true?

If I can install OpenSolaris as the master, which distribution should I download from the SGE download site
(https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_SMI-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=SunGE-6.2U5-G-F <at> CDS-CDS_SMI )?

Thanks

I spent a fair bit of time writing proposals (yearly server replacement 
justifications, etc.), trying to resolve Veritas' insane licensing 
system that never referenced the server or license, and in meetings of 
various sorts.

Re: Sun Grid Engine on OpenSolaris

Hi,

Yes this is correct because the queue masters have to be Solaris/OpenSolaris on SPARC which is not an option
on AWS. You could host that internally and then have all of your execution nodes running on AWS.

Comstar config at boot

Hi,
Could any one tell me if there is a way to keep comstar config permanent so that when we boot a new machine from a
cloned image of open solaris i get the config i had previously saved. 

For example, I want to have say 64 LUNs of 32Mega Byte size created with ramdisk and mapped to some hosts. All
these luns are made available using comstar target mode. Now i want to cloned this image using some tool
like clonezilla and later boot new machine with this cloned image to get the same config. 

Is that a feasible. 

Thanks in advance for the help.

Re: ELOM Console failure

It appears that you need access to TCP port 8890 (in addition to 443/https) for the remote console.

Installation Hangs after reboot

Hi All,
I have tried installing Open Solaris 2009-06 version into a x86 machine. All the installation steps gone
well following which i needed a reboot. I rebooted the machine and disconnected my CD media drive when the
system was coming online. After it came online, the machine hanged. I could not login. Following message
was displayed at the console terminal. 

[i][b]opensolaris console login: Jan 7 17:09:44 opensolaris is routed[390]: route 0.0.0.0/20 -->
0.0.0.0 
nexthop is not directly connected[/b][/i] 

Not sure what is causing this. Any help is appreciated. I have done installation of two different versions
of O Solaris SXCE (build 122 and 127) but never seen this before.

Thanks,
