HP P6000 EVA Updating Product Software Guide (XCS 11001100) (5697-2328, November 2012)

NOTE: OpenVMS tolerates the controller reboot that occurs at the end of the controller software
upgrade process. Disks on the controller display the Mount Verify status during the controller reboot
but return to Mounted status and resume I/O operations when the controller reboot is complete.
You do not need to change any OpenVMS default settings when performing an online controller
software upgrade.
Online controller software upgrades are supported in OpenVMS cluster environments where the
array is the cluster boot device.
Solaris
Solaris supports online controller software upgrades with the following driver timeouts:
• Sun drivers (qlc or emlxs): 60 seconds
• QLogic (qla2300): 60 seconds
• Emulex (lpfc): 60 seconds
Checking or changing timeouts
For Sun drivers, add the following lines to the /etc/system file:
set sd:sd_io_time=60
set ssd:ssd_io_time=60
For the QLogic driver, edit the /kernel/drv/qla2300.conf file and change the
hbax-link-down-timeout value to 60:
hba0-link-down-timeout=60;
For the Emulex driver, edit the /kernel/drv/lpfc.conf file and change the linkdown-tmo
value to 60:
linkdown-tmo=60;
VMware
VMware ESX (Hypervisor) timeouts
VMware ESX (Hypervisor) does not time I/O for a guest operating system. Therefore, the SCSI
timeouts on commands issued by each VMware guest (Linux, Windows, Solaris) are the timeouts
set for these systems.
Using HP P6000 Command View on a Windows 2008 guest system on ESX 4.1 or 5
When using HP P6000 Command View on a Windows 2008 guest system on ESX 4.1 or 5, use
one of the following methods to upgrade the firmware to ensure a successful upgrade, or your
array code load will fail in a VMware Guest OS configuration:
• Array-based management module
• Physical server-based HP P6000 Command View
• Direct Path I/O mapping from ESX (requires supported hardware on the ESX server)
Xen Citrix
For Xen Citrix, (except for NFS SR timeouts because Citrix XenServer 5.0 mounts using software
with nondefault timeout values) use the values described in “Linux Red Hat and SUSE” (page 29).
To check or set Xen Citrix parameters, use the set_parm executable located in the
/opt/hp/<driver>
directory. When executed, the options to change timeout values are displayed.
