Hi,
We are trying to configure a split bus configuration with 2 ESMs and 2
hosts on a D2. The 2 hosts are a v880 and a 280r running on solaris 8.
There are 8 disks in the D2, 6 for ESM0 and 2 for ESM1.
During installation, power to the D2 was kept on. The customer insisted
on keeping the power on to the D2 for some reason.
The D2 initially had one ESM connected to the v880. A second ESM was
then installed into the D2 (whilst still powered on). The Configuration
Options Switch 1 was later set to down as directed in the manual.
So, we have ESM0 connected to the v880 and ESM1 yet to be connected to
the 280r.
Next step was to run the "devfsadm" command.
We then proceeded to check the split-bus config on the v880 by checking
if the disk device names changed from cXt0dY-cXt5dY to cXt8dY-cXt13dY by
using the "format" command. The device names still remained
cXt0dY-cXt5dY.
Even though ESM1 is not connected to a host, I believe the device names
on the v880 should still change to cXt8dY-cXt13dY.
Any ideas on why this is so? Does the D2 need to be turned off and on
to detect the second ESM and to make split-bus switch configuration
option take effect? Or is it smart enough to do all of this on the fly?
Have I missed out anything ? If so, any advice would be greatly
appreciated.
Thanks and will summarise.
