1) Yes you can upgrade fro OneFS 6.x to 7.0.  You need to follow the proper procedures and make sure that your cluster is ready for the upgrade.  There is a checklist document for doing the upgrade.

2) RestAPI is available in OneFS 7.x.  There are no plans to backport to any earlier version.

3) No current command to get the equivalent of isi status.

4) No command yet to query the node type.

5) No.  JSON output is not available for pre OneFS 7.

> 4. is there an command/URL to see the which type of the node  (which series it belongs to)

>> No command yet to query the node type.

# isi_hw_status | grep ^Product

Product: S200-2U-Dual-48GB-2x1GE-2x10GE SFP+-13TB-400GB SSD

Thanks for your replies.

One more query, Is there any api and/or command which gives nodes' disk drive details like disk type, its rpm value and its size.

"isi status -n" is jsut giving disk name ,status and speed

Not sure for rpm, but lots of static and SMART information are available through:

isi devices

isi_drivenum [-h for options!]

isi_radish [-h for options!]

Live activity monitoring:

isi statistics drive --long [also -h for more options]

-- Peter

isi_for_array -s isi_hw_status | grep Product:

-- Peter

Thanks again, Is there any command to see all the models of all the nodes.

our one of node model from management interface.is

Model:  Isilon X200-2U-Single-6144MB-2x1GE-2x10GE SFP+-6144GB

Is there any (single) command we can run and see models of all nodes in the cluster
