Device Commands - IBM TotalStorage DS300 Best Practices Manual

iSCSI IP failover policy: remote
'Logged into controller' means the controller that the Telnet or serial session was
started on.
The 'Working on' controller can be changed with the controller set command.
controller set controller
Set the current controller. The controller value can be A or B. The current Telnet
or serial session will remain logged into the controller it started with.
ipfailover local | remote | both | none
(iSCSI only) Set the policy for the failover of iSCSI interfaces, using these
options:
local - if an interface fails, an interface on the same controller will be chosen
if possible (ETH2 → ETH3 or ETH3 → ETH2).
remote - if an interface fails, an interface on the other controller will be used
(ETH2 → ETH2 and ETH3 → ETH3)
both - if an interface fails, attempt to failover to an interface on the same
controller (ETH2 → ETH3 or ETH3 → ETH2). If an interface on the same
controller cannot be used, an interface on the other controller will be used
(ETH2 → ETH2 and ETH3 → ETH3).
none - no failover of iSCSI interfaces will be attempted.
Note: The default setting is Remote failover option.
peer enable | disable
Specify enable to bring up the other controller.
Specify disable to take down (halt) the other controller. This takes a while, so
you must keep looking at 'controller info' to check on the status of the other
controller.
A.9 Device commands
These commands control device discovery. You can use these commands after a
device command with no parameters, or as global commands by preceding them
by device.
