Another device naming technique
This technique is an alternate device naming technique that applies only to DASD devices.
The example in Too many DASDs accessible to Linux for read also
shows a strategy to force the different Linux systems on the cluster to use the same
name for the same devices. For example, disk device 7c85 is named /dev/dasdg on
both nodes in this cluster. Towards the end of the line that begins
with
parameters= is the parameter dasd=
with associated devices: dasd=7435,7436,743a,7535,7536,7c84,7c85,753a,78b4,79b2,7ab2,7c83,7ab4,
7caf,79b3,79b4,7cb0,7cb4,7db6,7eaf,7eb0,7ab6,7137,7239,7339,7539,7bb2On system restart, the DASD devices are named in the order shown,
with the dasd= parameter, starting with /dev/dasda and
ending in this case with /dev/dasdaa. Modify
the DASD parameters of the other servers to have the matching names
required. This method applies only to DASD devices.
