i just tried to install latest Host Utilities 5.2.1 on my DL 380 G7 with vsphere 4.1 like i did with all my other esx. since i wanted to enable alua on the host i needed the host utilities. installation fails with HBA not installed. But on the other hand, i can use the HBAs fine in vsphere Client and see all my LUNs. what could be the problem or how do i get ALUA to work ?
Additional info: Netapp Virtual Storage Console does not set the recommendet settings if i use the GUI, any idea if that has something to do with it ?

I don't think you need host utilites to use ALUA today. How do you mean VSC does not do the setting? Did you provision a datastore with VSC? If I check the TR-3749 (vSphere best practices document) it says:
"For iSCSI, FC, and FCoE datastores, the VSC handles storage access control by creating initiator groups, enables ALUA, applies LUN masking, applies path selection policies, and formats the LUN with VMFS."

Basically i went through this: http://blogs.netapp.com/storage_nuts_n_bolts/2009/08/vsphere-upgrading-from-non-alua-to-alua.html
I had the 5.1 Utils installed on all ESX before without problems. I enabled ALUA on my igroups, then applied
esxcli nmp satp setdefaultpsp --satp VMW_SATP_ALUA--psp VMW_PSP_RRand then it was visible in vcenter that its using RR via ALUA.now on the new host utils those 2 HBAs are "not installed" according to the host utils, even if they are working fine BUT RR/ALUA is not working for these 2 hosts.with VSC does not do the setting i mean: ESX hosts show me Alerts on Adapter Settings and MPIO, like QFullSampleSize 0 (Recommended 32) and if i wanna use VSC to "right mouse click -> Set recommended values" nothing happens, it stays on Alert
