[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: Target ResetThis is at least better. But I do not have the issue of it being vendor unique. This is a shut down and restart of the complete Target, and will probably be part of the vendors' operator console or their own remote support functions, it is not clear that it needs to be a general management function that works the same on all iSCSI Storage Controllers. Many of the major Storage Controller do not support this feature today. I do not believe that most SNMP implementations are very secure. Most folks do not want to have a changeable MIB until they have secure SNMP, and even though there is a version of SNMP that has security features, this has not been well supported. I do NOT think that Target Reset should be in the base iSCSI protocol, but I think it is reasonable to hold this discussion apart from the base protocol document, and the question should be asked if this is a general management function or a vendor specific console or remote support function. . . .

However, looking at this from a management perspective I'd like to see a standardized way of resetting a target. I don't want to see a variety of vendor unique methods of resetting targets sprout up. If resetting a target using the protocol is not desirable from your perspective would incorporating this feature into the MIB be acceptable?

I thought there was general feeling that this command is so dangerous that it should not be supported by iSCSI. The long distance capability of iSCSI makes the risks involved unmanageable. There should only be an Admin way to do this. Some folks have said that we could permit it and have special authorization etc. This would probably cause a separate section in the spec. to define the authorization approach, and what ever other security is needed to prevent this from inappropriately being used. All for what purpose? This can not be part of error recovery from a normal initiator. The wide spread effect is too great for that. I would like to hear from the list about their feeling on this item. . . . John L.
