Using Windows DMP
When you use Windows 2000 DMP for CLARiiON, you need to take
into account the following behaviors for LUNs under DMP
management:
◆ After Windows 2000 reboots, one SP owns all the LUNs. If you
want the other SP to own any LUNs, you must manually transfer
ownership of (trespass) those LUNs to the other SP using the
Navisphere Manager or CLI.
◆ Windows DMP for CLARiiON does not support auto-restore for
LUNs. If a failure occurs in a path to an SP, Windows DMP
transfers ownership of LUNs to the other SP, but it does not
transfer ownership back to the original SP when the path is
repaired. The server does not lose access to the transferred LUNs.
If you want the original SP to access any LUNs for load balancing,
you must manually transfer ownership of those LUNs back to the
SP using the Navisphere Manager or CLI.
◆ If I/O is occurring between a server and a LUN, you cannot use
Navisphere to transfer ownership of the LUN from one SP to the
other SP.
◆ Adding more than 40 LUNs to a Storage Group may cause
Windows 2000 to crash.
◆ The Navisphere Host Agent does not register host information
with the storage system correctly.
