SPcollect for both SPs
Hi can someone explain to me why we need an SPcollect for both SPs and not only for SPA or SPB. As I understand both SPs access the same disks and have the same configuration except IP address? My question may seem a bit weired but I'm new in this field and I want to understand this first before moving forward.

Each SP 'owns' a set of LUNs, and a LUN is only active on one SP at a time. (for Clariion anyway)
Really, this makes sure that SP resources (cpu, memory and cache) are used appropriately.
Therefore if you only gather a single SP's collects, you're not going to get all the logs/captures and info about the LUN's the other SP has active on it, and you won't be getting the full picture.
When you look at a LUN's properties you will see the Current owner and the Default owner. When a LUN is not on it's default owner, it's 'trespassed'. In the event of an SP failure, all LUNs on the failed SP would trespass to the peer/surviving SP.
You may also see 'Allocation Owner', which for Pools, manages the slice allocation.
Ideally you want the allocation owner, the default owner, and the current owner to all the the same SP.
I've digressed a bit from your question, but hope the info helps.

Oh heck, you don't need cables! Do this from the Unisphere GUI.
Go to the system tab, then down the right you'll see "Diagnostic Files". Generate the files for SPA, then SPB then come back in 10 minutes and run the "Get Diagnostic Files" wizards.
Can also be done form cli if you're that way inclined (I am). So if that interests you, happy to help you with that later on.

Thanks, Another question : is there a way to get SPA and SPB SPcollect simultaneously without logging out from SPA after generating Diagnostic files, switch the cable and log in SPB Generate files, get them and then switch back cable to SPA and get files from SPA.

Navisphere Secure CLI
Perform the following steps:
This will display the files that can be moved from the SP to the Management Station.
Example:
Index Size in KB Last Modified Filename
0 339 06/25/2013 00:45:42 admin_tlddump.txt
...
10 24965 06/24/2013 23:39:53 FNM00125001234_SPB_2013-06-24_22-38-15_32a007_data.zip
11 41577 06/25/2013 00:17:17 FNM00125001234_SPB_2013-06-24_23-10-55_32a007_data.zip
...
This will pull the index number 10 (the most recent ~_data.zip file) from the corresponding SP and copy it to the c:\program files\emc\navisphere cli directory, with a filename of FNM00125001234_SPB_2013-06-24_23-10-55_32a007_data.zip
