https://community.hpe.com/t5/operating-system-vmware/vsa-amp-scsi-presistent-reservation-requirement-of-esx/m-p/4596259#M648 Hi All,<BR /><BR />I am using HP servers running ESX4, and has qlogic/Emulex HBAs.<BR /><BR />We have a large FC storage (SAN) that doesn't support scsi persistent reservations that is required by ESX.<BR /><BR />We want to use this storage on our ESX servers (no clusters), and we are looking at ways to over come the scsi reservation requirement of native ESX.<BR /><BR />If I install VSA on the ESX, does it take control over the SCSI layer of ESX ? <BR /><BR />Does VSA require scsi persistent reservation toward the block devices (SAN) <BR />(Which leave me with the same problem) <BR /><BR />Or it doesn't ? <BR /><BR />and that solves my problem, and I can use that storage, and even gives me additional value of storage virtualization.<BR /><BR />In this manner the VSA will provide the scsi reservation toward the ESX, but will enable me to use my storage, that doesn't support scsi presistent reservation.<BR /><BR />Any advise would be useful <BR />Thanks !!<BR />Ron Sun, 07 Mar 2010 12:19:13 GMT carmelim123 2010-03-07T12:19:13Z https://community.hpe.com/t5/operating-system-vmware/vsa-amp-scsi-presistent-reservation-requirement-of-esx/m-p/4596259#M648 Hi All,<BR /><BR />I am using HP servers running ESX4, and has qlogic/Emulex HBAs.<BR /><BR />We have a large FC storage (SAN) that doesn't support scsi persistent reservations that is required by ESX.<BR /><BR />We want to use this storage on our ESX servers (no clusters), and we are looking at ways to over come the scsi reservation requirement of native ESX.<BR /><BR />If I install VSA on the ESX, does it take control over the SCSI layer of ESX ? <BR /><BR />Does VSA require scsi persistent reservation toward the block devices (SAN) <BR />(Which leave me with the same problem) <BR /><BR />Or it doesn't ? <BR /><BR />and that solves my problem, and I can use that storage, and even gives me additional value of storage virtualization.<BR /><BR />In this manner the VSA will provide the scsi reservation toward the ESX, but will enable me to use my storage, that doesn't support scsi presistent reservation.<BR /><BR />Any advise would be useful <BR />Thanks !!<BR />Ron Sun, 07 Mar 2010 12:19:13 GMT https://community.hpe.com/t5/operating-system-vmware/vsa-amp-scsi-presistent-reservation-requirement-of-esx/m-p/4596259#M648 carmelim123 2010-03-07T12:19:13Z
