Can i install Dell MEM in anytime ? or need close all vm on EQL ?

Hi Don,

If i don't know how to install Dell MEM (Because I am unfamiliar CLI or Script),

Then I can try,1). disable DelayedAck ? 2).change the IOs per path to 3 from default of 1000.?

I checked the MPIO is set to Round Robin,and can i change IOs per path value in vCenter GUI ?

Thanks for your reply,

Ken

The MEM manual also offers the option to install it with the VMware Update Manager. You'll want to create a baseline and then you attach it to each of the hosts. Now you remediate and apply the updates. The remediation will require the host to be in maintenance mode.

If you are running an Essentials, Essentials Plus or Standard VMware license, installing MEM isn't an option (VMware licensing restriction). In that case you'll want to use Round Robin and change the IOs per path value to 3 like Don mentioned.

Hi Dev Mgr,

Thanks for your reply,

I try to use the VMware Update Manager, and create a baseline and then attach it to each of the hosts,

But it show the (?), I don't know what the problem?

I will select some time to remediate it, Because I only have one EQL.

PS.I have Enterprise License for VMware vSphere 5.5

Hi Don,

I use the VMware Update Manager to install DELL MEM,then the Round Robin is auto set,

And I disable DelayedACK, no other steps..

Now I will try the VMware vMA to run setup.pl,

And installed vMA,But I have no idea how to copy and run the script....

please HELP .. Thanks

Ken

Hi Don,

I have a question,

If the MEM is finish install to ESXi HOST,How can I check it??

And if MEM is installed,Then I need to run setup.pl from vMA too? or no need?

Ken

Hi Don,

YES, All  EQL Datastores will show DELL_PSP_ROUTED,

But why vsphere show "performance has deteriorated" warning,too ?

Thanks for your reply~

Ken

Hi Don,

Thanks for your reply,

I will try this to check DelayerACK,Then report to you~

If installed MEM,Then I need to delete "Static mappings" all link,

And setting disbale DelayerACK and Login_timeout to 60

Then rescan all link form Static mappings ?

Thanks~
