Hi,
I don't know if this is the right forum, but I think it's driver
related.
I use mpt_sas driver to connect my front-bay SAS disks, mpt_sas is
configured to use MPxIO.
If I pull out a faulty zpool disk, I always have a "drive type unknown "
entry in the output of "format" ,
Putting a new disk into the same SAS bay does not remove that entry.
0. c1t5000C50028C8B377d0 <SEAGATE-ST3600057SS-0006-558.91GB>
/scsi_vhci/disk@g5000c50028c8b377
1. c1t5000C50028C89B5Bd0 <drive type unknown>
/scsi_vhci/disk@g5000c50028c89b5b
The only way to get rid of this entry is to put the same disk back, or
maybe reboot can get rid of this entry, but I haven't tried.
However, if I pull out a disk that does not belong to a zpool, I don't
have this entry in "format".
I understand that each SAS disk has its own GUID, and when MPxIO is
enabled, Solaris uses
That GUID as part of the OS path, that explains why putting a new disk
into the bay does not remove the old entry,
But why removing a disk leaves a entry in format, shouldn't devfsadm
remove that path ?
Is this a known issue for SAS disk? or Did I miss anything
configuration-wise ?
How can I remove this entry without reboot ?
Thanks
