Darren, I agree with Alan's proposal that the existing system extended attributes be expanded to include "offline" or whatever the appropriate tag could be. This would require a change to SAM-QFS to support Solaris extended attributes in at least the case of that flag (a SAM-QFS project/case, I'd guess) and modifying the interfaces introduced in PSARC/2007/315 to include the newly defined flag. This case appears to be asking to use existing interfaces of SAM-QFS to cause the Solaris provided samba to detect a condition that is causing the described customer problem, and mitigate it. The resultant FILE_ATTRIBUTE_OFFLINE within the SMB_QUERY_FILE_BASIC_INFO appears to be standard (at least in the SNIA document). I would think that advise to the PAC about modifying SAM-QFS to at least support an system extended attribute for offline, and for some unknown group to add that to the existing system extended attributes would be an appropriate response. In the mean time, I would think this case could be approved with a TCR to modify the version of Samba shipped by Sun when the architecturally appropriate interfaces (those using the existing infrastructure described in PSARC/2007/315) exist in Sun current and future HSM products. I could help add this to the general opinion, or add it as a minority opinion. == Rick
