Hi folks.
We want to move a "physical" AIX box to a VIOed LPAR. The physical box is running SDD with disks from a DS8300. I want to be able to reattach those LUNs from the DS8300 to my VIO server which is running SDDPCM and then assigned them back to my AIX LPAR. Any thoughts about this?

I was wondering if there is a way of auto-detecting a new vpath, using IBM's SDD driver, on a Linux platform.
ON AIX it is a simple as running cfgmgr.

NAME
scsimgr_eschgr - SCSI class driver eschgr plug-in for scsimgr
DESCRIPTION
The SCSI class driver plug-in for implements management and diagnostic operations specific to classes of devices bound to the driver. is
the native HP-UX SCSI class driver that handles, by default, all library/changer devices.
The plug-in handles the following operations for driver
o Display and clear driver global statistics and the statistics it maintains on instances of LUNs bound to it, and on related LUN paths.
o Display status and other information maintained by driver on LUNs bound to it.
o Get, set and save driver global and per-lun instance attributes.
Commands
The user can explicitly send the following commands to driver plug-in by specifying the
Clears statistics.
Displays information on attributes.
Displays status and other information.
Displays statistics.
Saves value of attributes in a persistent store.
Set current values of attributes.
Note: Refer to scsimgr(1M) for the syntax of the above commands.
However, the only instances where it is necessary to explicitly send a command to the plug-in is when performing operations on objects
global to driver global statistics, attributes or status information. In all the other cases, automatically invokes the plug-in to perform
the driver specific part of the operation, when the operation applies to LUNs bound to driver or to their LUN paths.
Attributes
The following table lists driver specific attributes. For details on the concept of attribute refer to scsimgr(1M).
Note: The following conventions are used:
o RO is Read Only.
o RW is Read Write.
o uint32 is unsigned 32 bits integer.

Default: 600
----------------------------------------------------------------
exchange_secs RW uint32 Timeout for the
exchange command.
Default: 600
----------------------------------------------------------------
I/O Load Balancing and Multi-Pathing Policies
The driver does not support load balancing and has minimal support for multi-pathing.
When the device is first opened after a system boot, a path is chosen and will remain fixed. If the path fails, the next open will pick a
new path.
EXAMPLES
To display plug-in general help and supported commands:
To get driver global statistics:
To clear driver global statistics:
To get driver global status information:
