To change Path TOV value (repeat for all ports) follow the example below. Also this command can
be included in ESX host startup such that it will be run automatically.
# esxcli brocade bcu --command="fcpim --pathtov 1/0 14"
path timeout is set to 14
To query a port# after a change was made, follow the example below:
# esxcli brocade bcu --command="vhba --query 1/0"

Installing Virtual Machine Guest Operating System
The VMware ESX host documentation lists recommended virtual machine guest operating systems
(GOS) and their installation and setup as virtual machines (VMs). Refer to the VMware ESX host
documentation for information on setting up your virtual machine configuration.
CAUTION: In VMware KB 51306, VMware identifies a problem with RHEL 5 (GA), RHEL 4 U4,
RHEL 4 U3, SLES 10 (GA), and SLES 9 SP3 guest operating systems. Their file systems may become
read-only in the event of busy I/O retry or path failover of the ESX host’s SAN or iSCSI storage.
KB 51306 is available on the VMware Knowledge Base website:
http://kb.vmware.com
Because of this known issue, HP does not recommend, and does not support the usage of
RHEL 5 (GA), RHEL 4 U4, RHEL 4 U3, SLES 10 (GA), and SLES 9 SP3 as guest operating systems
for virtual machines on VMware ESX hosts attached to HP 3PAR StoreServ Storage systems.
CAUTION: The use of the N-Port ID Virtualization (NPIV) feature introduced with VMware ESX
3.5 - 5.0, allowing virtual ports/WWNs to be assigned to individual virtual machines, is not
recommended and not supported with the HP 3PAR OS.
