I am much confused about possible usage of SDDPCM on my latest VIO server. The VIo server is running latest version of VIOS and backend disk subsystem is DS5100.
Question is that whether i require SDDPCM on VIO server or not? If not , which device driver for DS5100 should i put in VIO server? If i dont put any MPIO driver on my VIOS server , will mutipaths to DS5100 and failover will work?
The confusion arises from following IBM website which says SDDPCM is not supported on VIOS with IBM DS5000 series.http://www-01.ibm.com/support/docview.wss?rs=540&context=ST52G7&dc=DA400&uid=ssg1S7001350&loc=en_US&cs=utf-8&lang=en#AIXSDDPCM
