EVA raid controller lun 0 Multipath Policy

[griswld]

All of our vSphere 4 update 2 luns are currently set to use round robin except for the controller lun 0 - it is set to fixed. Should lun0 on a eva 8000 /8100 be set to round robin as well? The luns are currently using VMW_SATP_ALUA and the raid controller lun 0 is set to VMW_SATP_EVA psp, is this correct? Thanks in advance.

correct, this controller lun does not support ALUA,

Binoche - you are saying that it should be set to Round Robin? Also can you explain what you mean about the lun 0 not supporting ALUA? Does this mean we will be passing data down the preferred and non preferred controller paths with Round Robin?

TIA

1, leave this controller lun to continue to use FIXED

2, when ESX scans out this lun, it reports not support to ALUA

3, this is management lun and 0MB in size, not for datastore
