MSA 2000

I have MSA 2000 disk array that has volumes defined, and I want to know if I can address those volumes on demand from my laptop using the iscsi initiator.  These volumes are in use by several other machines, and I don't want to adversly impact thos machines.

Unless you encounter permissions issues, you should be fine using your laptop.
If you change the subnet mask to, you should be able to access the .99.x from the.1.x computers.  If they are on separate routers, you may need to port forward TCP ports 860 and 3260 to the iscsi or computers, depending on which device is on the WAN side of the router.

Also, if my iscsi network is seperate, i.e.

production - 192.168.1.x
iscsi - 192.168.99.x

is it ill advised to 'bridge' these networks via a 'router' so that in extreme cases, machines on production networks can map iscsi volumes as needed?

It is important to note that accessing the volumes from several separate hosts may cause data corruption.

Ditto on that Arthur, corruption is inevitable unless they unmount them first from the machines using them which would adversely affect the production machines.
Yep andy, I should have elaborated on my comment.  

Some folks think that they can use a san directly as a shared disk space among several hosts.  They don't realize that the san doesn't have the file locking and protections that are part of the NFS or samba disk sharing systems.

So, it should be noted that sharing a volume on more than one host at a time, will cause data corruption.

thanks for the following:

1. answering the question
2. identifying risks/gotcha's
3. elaboration

point distribution was hard, because it was all valuable.  Hope you find my choices fair....
