Thanks for the quick response. We had taken a look at the relationship between major and minor but dismissed that method based on the following.
In SAR we were able to identify five devices. >From SAR... dev8-0 dev8-1 dev8-2 dev8-3 dev8-4 In IOSTAT five devices are identified, sda, sdb, sdc, sdd and sde. >From IOSTAT... sda sda1 sda2 sda3 sda4 sda5 sda6 sda7 sda8 sdb sdb1 sdc sdd sde Results from ls -l, looking at major and minor sda...8,0 sdb...8,16 sdc...8,32 sdd...8,48 sde...8,64 We might infer that dev8-0 is the same as sda, however, once we extend that method out to sdb, sdc, and so on, the major and minor numbers cease to provide a relationship. I was hoping to find a file someplace that provided the relationship.
