Solaris

Hi

I have NetApp lun, that was mounted on server as a file system that failed, and that server is no longer in use, but I would like to use that file system on another server. The NetApp Admin, told me he can present that lun to my other system, but my problem is how to mount it? Because that file system has already data, Looking forward to hear your comments

You will rescan the fabric and use mount command or import the zpool once the old lun is visible to new OS.

Just be sure it is not mounted/imported on other host(s) at the same time, since you will corrupt that data.

Also, additional steps might be required if Solaris SVM was involved (you have not specified what have you used on the former server).

Hope that helps

firstly its a ufsfile system that it will be unmounted on the old system. my query is how to mount it on the new system!
Do I have to use the formatcommand to see the LUN first? and just use mount command?

No, you shouldn't need to use the 'format' command and, indeed, it could be risky to do so (in case it writes anything to the filesystem eg, new label).

You have said that the filesystem is 'ufs' and I assume the connectivity is over Ethernet? Or is it fibre channel?

Assuming it's over ethernet then the NetApp has an ip address so you can prove the LUN's availability to your Solaris host with

Code:

# showmount <NetApp ip address>

This will show you any NFS handles that the NetApp is publishing that your Solaris host could access. If you see a NFS handle available and you have a local mountpoint (or you create one), you can issue the mount command directly.

If the above 'showmount' doesn't show the available NFS handle then your network storage boys haven't published it properly.

Hope that helps.

The connectivity is over fiber channel

Does the LUN show up in the disks listed by format? And is the new server of the same x86 or SPARC processor family as the new one?

If it's fibre channel then use

Code:

# luxadm probe

to see if it's listed in the devices the host can see.

The other problem you will have is that the device nodes (/dev/dsk/?, /dev/rdsk/? and /dev/cfg/?) won't have been created for this LUN. To create then use

Code:

# devfsadm -Cv

Once you have the device node in place you should be able to mount the LUN on a mountpoint of your choice.
