Hi Mrinal, sincere apologies this has taken so long, but I hadn't forgotten about you
The solution is below. We hadn't seen the issue above before and I don't know if it was something to do with new VMAX engines being put in and new arrays being used... the chassis we were using were also new and in pre-prod
Turns out when the C7000 switch was rebooted all the probes were reset and the WWNS disappear, hence the "seeing" problem. To get us to a state where we could see all the blades in the chassis we:-
went into the Emules BIOS for each server and set the fabric to point to point
each server was then reprobed and booted to the recovery CD
bingo, we could then see them all and we've had no issues since, all our storage is provisioned and we are using it for our O/S and software builds.
What is the interconnect on the blade your using and discovered on CM. BL-460s has many connectivity options and you need to check the compatibility of those with CM your running first. Basically network settings cause this kind of issues but you already checked them as mentioned. check for duplex setting on CM and if any discovery errors are getting logged or not ? If not then check java version too once. If you can give more details for interconnect and versions then we can check interoptability.
Sorry for the delay but many thanks for your helpful advice. We actually got to the bottom of the problem eventually. I have so many emails that I am struggling to find it right now ... once I do I will post what our problem was.
