Hi All,
Need help with external storage virtualization
How to properly connect external IBM DS4800 storage system to HUS VM?
What is a minimum number of ports needed from both sides (assume the availability of alternate paths)?
PS: DS has 2 CTL, each of them has its own LUNs assigned.
My assumption is: 4 paths - 2 for I/O (one from each CTL), and 2 for Alternate Paths. Is this correct?
pls ignore about loop connection...if you do this to active path, then your server will lost connection... a dedicated port refer to HUSVM for virtualization. You may follow the steps:
1) change HUSVM port to external
2) zone external HUSVM port with active DS4800 port from san switch
3) create a lun in DS4800
4) zone the lun with HUSVM wwpn in DS4800
5) scan the lun added in DS4800 from HUSVM
6) assign culdev of detected lun
Hi, thank you for advice.
Situation is slightly different,
Existing storage system already contains the LUNs (with data).
Half of them are accessible via first controller (CTL), the other - through a second controller (for balancing purpose).
So, each controller are "active" for their LUNs.
UVM support only "single path mode" for DS4800, that's why I suggested that it is necessary to have 4 paths - 2 for I/O (one from each CTL), and 2 for alternate paths (also one from each CTL).
hi ove
you must have a dedicated port to connect to HUSVM for virtualization. min 1 port for virtualization..however you must connect to active path from DS4800 to HUSVM..either direct connect (loop) or switch connect.
