Works 100% ESXi 5.1

HBA (LSI 1064e) > 1x SAS2 100GB SSD

Doesn't work ESXi 5.1

HBA (LSI 9211-8i IT /IBM M1015) > 1x SAS2 100GB SSD

After a few hours of heavy HD load i get: - Device or filesystem with identifier ['all drives'] has entered the All Paths Down state. - ESXi retries but loses connectivity to the SAS drive, marks it as "dead or error" - reboot fixes the issue

How can i fix this issue?

Are you using the 9211i as an HBA or as a RAID controller? – ewwhite Sep 20 '12 at 12:40
HBA, 2x SATA2 2TB (RDM), 100GB SAS (esxi datastore) – user1434058 Sep 21 '12 at 13:11
Did you update the firmware on your LSI controller? – ewwhite Sep 22 '12 at 13:37
yes, P14 IR firmware (does IT also) – user1434058 Sep 23 '12 at 14:14

Update the ESXis LSI 9211-8i driver. VMWare is shipping v.10 and we are at v.14. This update resolved a lot of issues for me.
