Agile Devices on 11.31 - ?

[Alzhy]

Anyone want to explain what this is all about and if it is something we need to be concerned about?

We're having a new RX6600 server to serve as our new NBU 6.5.1 NBU Master/Media Server and Symantec has warned us of certain issues.

We're 11.31 Noobs.. although we've had a small Itanic RX2660 turby for a while that we've used with no FC connections and it just act as a file server and Ignite Server at our DR site. so we've not done much exploration on 11.31

Hey Nelson,

(short version)
11.31 has a new IO stack that includes multipathing by default.

No longer would you use /dev/dsk/cxtxdx ( they are still there but..) the new device name is /dev/disk/diskX. This new device file takes into consideration /dev/dsk/cxtxdx and its potential alternate path.

Configurable or by default the diskX file will pick any of the paths based on policy, round robin, load, queue, etc..

There is a white paper on docs.hp.com that is worth reading.

insf -m XX is a new switch to show you the mapping.

scsimgr ( i believe) is there to admin the config of the agile.

Symantic always has issues, whats new, any idea on what the issues are ?

I am sure others will post more...

Hi Nelson:

The quick overview of agile devices is:

http://docs.hp.com/en/LVMmigration1/LVM_Migration_to_Agile.pdf

There are quite a few other whitepapers relative to mass storage and LVM version-2 on the docs.hp.com site worth reading too.

Regards!

Can you share these "issues" with us? As already pointed out Symantec like all ISVs would rather no-one ever upgraded anything except their own product...
