There aren't any Dell|EMC 'approved/certified' applications to do that. There are tools out there that can do it, but Dell and/or EMC doesn't back, support or recommend (officially) any of them.
If you're running RH3, and have the SAN drive (LUN) set up as a logical volume, it's fairly easy to extend that volume using the volume manager. Keep in mind that the 2.4 kernel (really the scsidisk driver that comes with that kernel) doesn't particularly like (read: won't work porperly on the long term) drives 1 TB and larger.
Hmm, from my initial thoughts, using an LVM doesn't seem like a good approach. From the OS perspective, an LVM is composed of physical volumes. Each of these physical volumes is a Virtual Disk on the AX100. If you add a disk to the Virtual Disk, can an LVM be resized? Otherwise, you'd have to create a 2nd Virtual Disk, and append it to the LVM instead.
If we add a disk at a time, the LVM will have to be composed of a bunch of Virtual Disks (one each for every disk added), which seems really really messy to me.
Im a little spoiled coming from the Netapp world, but this is an expected issue as a DAS device is independent from the filesystems contained on its disks.
There are some 3rd party tools that can resize partitions on the fly. None will be Dell|EMC supported/certified, but programs like partition magic come to mind. The problem with partition magic is that it's dos and/or windows based. You could use the dos version, but in dos no Qlogic drivers will be loaded, and the LUN(s) won't be visible to dos, and therefor not to Partition Magic either.
I'd look for similar programs that are Linux based.
