LUN Uses Used by
------------------------------------------------------------------------------
D10 DISK60300
LUN ID: 6000-1FE1-0000-1530-0009-9231-4229-009E
NOIDENTIFIER
Switches:
RUN NOWRITE_PROTECT READ_CACHE
READAHEAD_CACHE WRITEBACK_CACHE
MAX_READ_CACHED_TRANSFER_SIZE = 128
MAX_WRITE_CACHED_TRANSFER_SIZE = 128
Access:
BUILDNGBA, BUILDNGBB, BUILDNGBC, BUILDNGBD
State:
ONLINE to the other controller
PREFERRED_PATH = THIS_CONTROLLER
Size: 35556389 blocks
Geometry (C/H/S): ( 7000 / 20 / 254 )
I 16. Delete the LUNs involved (refer to callout 9 on Figure 13). Use the commands:
DELETE UnitName
Example: delete d1
and
Example: delete d10
I 17. Re-add the LUN using the name of the original LUN (refer to callout - on Figure 13). Use the
command:
ADD UNIT UnitNumber ContainerName DISABLE_ACCESS_PATH=ALL
Example: add unit d1 disk60300 disable_access_path=all
CAUTION: Do not INIT the device. Loss of data may occur.
I 18. Enable host access to the LUN using the following command:
SET UnitNumber ENABLE_ACCESS_PATH=HostIDs
Example: set d1 enable_access_path=hosta
I 19. Turn the host port back on (refer to callout q on Figure 13). Use the commands:
SET THIS_CONTROLLER PORT_Number_TOPOLOGY=FABRIC
Example: set this_controller port_1_topology=fabric
SET OTHER_CONTROLLER PORT_Number_TOPOLOGY=FABRIC
Example: set other_controller port_1_top=fabric
Several completion messages display that confirm the link is established.
This completes the Non-Disaster Tolerant Data Movement to a Larger Capacity example.
