Hi.
Reading the SAF-TE spec iam getting confused if we need to do the following.
the PERFORM SLOT OPERATION comand 0x12h, bit 0 byte 2 of the write
buffer data mentions
Prepare for Operation Flag: This flag indicates that the SEP device should
take action required to make the device in this slot available on the
SCSI bus.
so when we perform a poweron probe, only the SEP device will show up, and
no attached disks will respond to SCSI commands? if this is true
then after we do a READ ENCLOSURE CONFIG->READ SLOT STATUS, determine
if a drive is there, then do PERFORM SLOT OPERATION, before we start the
drive probe?
Many thanks in advance
Cheers,
ashokr
