[Scst-devel] task mgmt in SCST

[T.Krishnanand <kri...@gm...>]

Hi,

Regarding Task mgmt support in SCST (more to do with SAM),

when a command has been submitted to the backend (eg; Linux SCSI ML)
since there is currently no way to abort such cmds..isn't it correct
to wait for such commands to complete before sending out the TM
response. These commands are guaranteed to complete since they have
timeouts (although not a very quick cleanup scenario).

with the current SCST approach, it doesnt wait for midlayer posted
cmds to complete.

If a write command has completed at the backend and theres an abort
request for it ... isnt it correct to "precisely" say if the cmd was
successfully aborted or not.

Currently SCST would let the cmd complete at the backend and say that
the abort was successful !!  IOW the cmd has finished execution (not
aborted) but initiator is being told that its aborted.

is this ok ?

PS: can someone point to the section in SAM which says this is
supposed to be handled by the intiator?

cheers,
