Increasing Lun and Solaris
Hi,
Under Solaris 10/Sparc I have full filesystems, I want
to to increase them and would like to know :
1) How I can increase Lun size at array level in a production system
2) How Solaris will know that the Lun had been increased
3) How to increase the filesystem in production or not.
Thanks for your answer

And what kind of volume manager do you use?
thanks

The storage is a Clariion.
I am not a specialist in Solaris, I have to check,
what I know is that the systems sharing the resources
are in a Veritas Cluster.
Thanks

The high-level plan for what you are trying to do is as follows:
1) Resize the LUN in the array (Expand LUN through Navisphere)
2) Get the OS to see the new LUN size
3) Get VxVM to see the new LUN size and increase the available space in
the disk group
4) Use the new space in the disk group to increase the size of a volume
5) Grow the file system on that volume to use the increased size
For steps 1, 2 please see the following example: http://tofu.org/drupal/node/77
If using VxVM, steps 3, 4, 5 are handled by vxresize command (man vxresize for usage.)
PS - I'm pretty sure you will have to at least unmount the FS's on this LUN when making changes such as this, therefore this is not an online change.
