adds support for multiple iscsi disks with the syntax:
root=<normal block path or UUID or LABEL> \
netroot=iscsi:... netroot=iscsi:... netroot=iscsi:...
which is suboptimal, because you can't specify it in the dhcp protocol.
A better syntax would be a single netroot (also for FCoE disk) something like:
netroot=netdisks:iscsi:...[separator]iscsi:...[separator]fcoe:...
What do you think? Any better ideas?

Note having this as netroot syntax and a separate iscsi_disk= for the one argument per disk case would be fine. Regards, Hans ^ permalink raw reply [flat|nested] 5+ messages in thread
