See comments below:  2. I need to assign all LUN to SP-A as there current and default owner ( No LUN in SP-B).  This is fine - the host  failover policy that is currently connected to the array will need to be changed (what the host will use as the default path to the LUNs once those LUNs are moved to SPA). This will end with the two blade servers with only a single path for each server to SPA. This is not recommended as you leave yourself open if SPA fails.  3. I need to disconnect cable of SP-B from server blades 0 and 1 , i want them to run with single SP-A.  Again, this OK but not recommended as a you now have a single point of failure for the two hosts.  4. I am connecting new Server blades 2 and 3 , want to use same EMC , so i will create new LUN and new storage group inside same EMC and will connect SP-B cables to those blades. Make current owner and default owner to of new LUN to SP-B and assign them new storage group.  Again this is doable and will work but again you leave yourself open if you have a failure.  I would recommend that adding a switch would help configure the array for more redundancy.  glen
Hello Team,  It is very urgent need , requiements  i have one EMC with attached to 1+1 cluster blades with A0 , A1 , B0 and B1 FC cables(no switch). I need to add two more new blades 1+1 in same chassis , but will use same EMC (no FC switch). I removed A0 and B1 from old blades and attach them to new blades , after this activity my veritas cluster was not coming up and veritas was no able to recognize the disk groups. LUN's were shuffling between SP-A and SP-B inside navisphere GUI.  After all this , i re-attach the cables and use some commands from here and there to again recongize my Disk Groups. It was done.  Now , i need to use same EMC for new blades , so now i am thinking to move all the LUN in SP-B to SP-A and give them current owner and default Owner, so no LUN left in SP-B . Now i will remove B0 and B1 cable from old blades and attach them to new one, create new LUN and make there owner as SP-B.   Will this thing will work perfectly. There will be no redundancy but this is fine as old blades need to be removed after sometime but while installing i require new blades connected with EMC with new LUN.  Please help me on this and provide your valuable suggestions soon.
Sp-A and Sp-B seperate connection
