ioscan output VA7400

[geeta]

Hi,

We are training on the VA products right now. had a lab today where we took out a disk and ran ioscan, however ioscan does not report any changes.From wht we learnt, i thought that ioscan should report NO_HW or something to indicate tht a disk was missing- but nothing. Then we put the disk back in, no changes..The funny part- no log anywhere- nothing in syslog, nothing on issuing logprn!!! What could be the problem? Why would ioscan keeo showing the same output with all disks claimed, no matter how many times we took a disk out? Can anyone help so I can go back in there tomorrow and finish the lab, plz!!!

What you are seeing through ioscan on the server are the LUNs not the actual disks on the VA. When you remove the disk from VA the LUN still exists because its the capability of VA to provide the LUN in the event of failure of any disk becuase of AUTO RAID implementation.

And the same applies when you see the logs on the server. Coz the server sees no difference as for it every disk is still seen thats why no logs say that the disk has been removed or failed. Its only on the VA controller or VA Admin page when you look at you'll see that a disk is missing or failed.

And how do i do tht? I mean wht commands would help me to find which disk is missing without knowing which one was pulled out?

Thanx rajeev :)

Hi Geeta,

You should have command view installed to do that and from the client when you run
armdsp -a you will see the status of the whole VA telling you the status of each component.

Alternatively if the command view is configured for GUI you can launch the launcher program which will detail you the VA status
