HP StorageWorks XP Remote Web Console Software - Manual (Page 35)

To turn ON the power supply of both arrays:
1. Turn on the power supply of the external array.
CAUTION:
Make sure that the power supply of the external array is completely on and then go on to the
next step.
2. Turn on the power supply of the local array.
CAUTION:
Make sure that the power supply of the local array is completely on and then go on to the next
step.
3. Resynchronize all HP StorageWorks XP Business Copy pairs (pairresync operations). For details
on the pairresync operation, see HP StorageWorks XP Business Copy user guide for
XP12000/XP10000 Disk Arrays and SVS 200.
4. Start the read or write I/Os to the local array.
All read and write I/Os with Fibre Channel connections, iSCSI connections, and NAS connections
should be started.
Using mapped external LUs from the host connected to the
local array
The following sections describe examples of using the mapped external LU from the host connected
the local array. There are different ways of using the mapped external volume.
• Writing new data to mapped external LUs
• Using existing data in mapped external LUs
Writing new data to mapped external LUs
Figure 9 shows an example of writing new data in the mapped external LU from the host connected
to the local array.
1. Use the XP External Storage GUI to map the LU in the external array as an internal LDEV of the
local array.
CAUTION:
Set the IO Suppression mode to Disable.
You can select the mapped volume's emulation type as required. If you select an emulation
type for an open-system (such as OPEN-V), go to step 2. If you select an emulation type for
a mainframe system (such as 3390-3), go to step 3
For more information, see Mapping external LUs (Add LU) .
