Technical Notes

iSCSI Devices

Take note of the following issues regarding native iSCSI devices

using the software initiator in a PowerPath environment.

Stopping iSCSI on a PowerPath Host

Always stop PowerPath before stopping iSCSI on a host with iSCSI

devices under PowerPath control. Use the following sequence of

commands to first stop PowerPath, and then stop iSCSI:

/etc/init.d/PowerPath stop

/etc/init.d/iscsi stop

Adding or Removing iSCSI Devices

You must stop iSCSI before you perform any operation that involves

adding or removing iSCSI devices. Examples of such operations

include adding or removing iSCSI devices from a CLARiiON device

group, or rebooting a CLARiiON SP that contains iSCSI devices

visible to the host. As mentioned above, you must stop PowerPath

before stopping iSCSI.

Issue the following commands to stop first PowerPath and then iSCSI

prior to any operation that involves adding or removing iSCSI

devices:

/etc/init.d/PowerPath stop

/etc/init.d/iscsi stop

After completing the operation that involved adding or removing

iSCSI devices, first restart iSCSI and then restart PowerPath. Issue the

following commands to restart iSCSI and PowerPath:

/etc/init.d/iscsi start

/etc/init.d/PowerPath start
