Hi everybody
We have a Sun Cluster with two nodes, connected to a number of SAN disks over fiber cables. We made SVM disk sets on those disks for our application needs.
Now we constructed another site in another metropolitan area, but with only one node (no cluster), and connected it to the main site through WAN. We replicated the LUNs from the main site to the secondary site.
Now the question is: Can I (and how can I) work with the replicated LUNs so that I can clone the application from the main site to the secondary site and let it see the disks sets, soft partitions...etc that were replicated?
You have the option of a geographic cluster - remote site + two local nodes.
Consider adding additional inexpensive (x86-based) "quorum servers" so you can have cluster failover.
Thanks for you reply. I am not talking about a planned architecture; I am talking about an installed and working one that I inherited. Changing the cluster type in the time being is not an option.
Let me rephrase: I need to see the up and running disksets that exist in the cluster in the DC in the same manner (same device names, data..etc) in a single node in another location.
I already tried metaimport -r -v but it returns "no unconfigured devices detected". What are my options? and why metaimport returns this message?

Ok guys I managed to solve it myself. For anybody reading this and looking for a solution here is the procedure:
(I am assuming that data has been replicated and that you do have read/write access to it)
Let's say you want to replicate disk set abc123 that has a number of volumes/soft partitions from machine main01 to machine dr01:
You need to have a clear and accurate mapping between the devices you have in the main site and the devices that was replicated to you in the DR site.
On the dr01 create a diskset with the same name as the original one on main01
Code:
metaset -s abc123 -h dr01
Start adding the replicated disks to the diskset in the same order as it was entered on main01 (you can determine this by running
Code:
metastat -s abc123
and see the order at the end.
On main01
Code:
metastat -s abc123 -p
This command will print the SVM configuration. Take a copy of all the output.
For every volume in the diskset you will see a line like the following
Hi Team,
I have written the shell script which returns the result of the disk space filesystems which has crossed the threshold limit in HTML Format. Below mentioned is the script which worked perfectly on QA system.

I need to generate exactly 102 duplicates in a file using sed.
Here's an example of my input:
Grid-ref = 1, 148
Grid-ref = 1, 311
Grid-ref = 1, 428
I need:
Grid-ref = 1, 148
Grid-ref = 1, 148
Grid-ref = 1, 148
Grid-ref = 1, 148
