https://community.hpe.com/t5/general/scsi-reservation/m-p/4576438#M4223 Hi,<BR /><BR />I have a problem with SCSI reservation in a IBM ESS (shark). Is there any command in HP-UX to delete the SCSI reservations in a SAN storage?<BR /><BR />thanks Tue, 02 Feb 2010 16:05:31 GMT Javier Martin-Lorente 2010-02-02T16:05:31Z https://community.hpe.com/t5/general/scsi-reservation/m-p/4576438#M4223 Hi,<BR /><BR />I have a problem with SCSI reservation in a IBM ESS (shark).
