P2000 G3: Modify Vdisk Owner causes VMware PDL

P2000 G3: Modify Vdisk Owner causes VMware PDL

Hi,

 

I've been testing out (our first) HP P2000 G3 10Gb iSCSI.  Performance is very good (22 disk Raid-50) in IOmeter, read, write, random, etc.

 

When doing failover tests with ESX 5.1:

- using 2 9000Mb/s vmk interfaces

- PSP: Round Robin

- SATP: VMW_SATP_ALUA

- 4 Active paths, 2 servicing I/O

 

I get good results when I:

- Shut down a controller

- Disconnect one or all 10Gb network ports on the controller

- Restart a controller.

 

However, when I move the vDisk from Controller-A to Controller-B I got a PDL (Permanent Device Loss) on the ESX server and things go to hell.

 

I should be able to move a vDisk to the other controller without causing an outage, right?

Re: P2000 G3: Modify Vdisk Owner causes VMware PDL

Hi,

 

I have this problem as well on a P2000 G3 SAS SAN, restart controller etc works great.

 

But when changing the owner manually, I have to do a rescan on the controller in VMWARE to get the volume up again
