Novell NetWare 6.5 Support Pack 5
EMC PowerPath


Symptoms: LUNs greater than 2000 GigaBytes accessed via PowerPath randomly deactivate. LUN access instability subsequently causes dependant NSS pools to randomly deactivate.


Corrective Actions: A LUN must be 2000 GigaBytes or less in size to enable proper LUN access through PowerPath

Additional Information

Notes: With out EMC PowerPath enabled, the total capacity limit of NetWare 6.5 Support Pack 5 SCSIHD.CDM is 2048 GigaBytes minus 512 bytes. Therefore the maximum usable LUN size for NetWare 6.5 Support Pack 5 without PowerPath should be less then or equal to 2048 Gigabytes minus 512 bytes.
