Hi, STK SL500 is only supported by TSM 5.3 server from the current doc from http://www-306.ibm.com/software/sysmgmt/products/support/IBM_TSM_Supported_Devices_for_AIXHPSUNWIN.htmldated Apr 2005. Do any one have any idea if the SL500 is supported by TSM 5.2.6 since it is released after the doc? regards, Calvin
