NOTE: For Microsoft Windows guests: set the windows SCSI timeout registry to 60secs, as follows: 1. In the windows registry, find HKEY_LOCAL_MACHINE\System\CurrentControlSet\ Services\Disk\TimeOutValue 2. Set this value to 60 decimal (3Ch). The ESX layer (VMFS, the VMware filesystem) controls timeouts of VMFS I/O. These values may vary from ESX release to release. Xen Citrix For Xen Citrix, except for NFS SR timeouts, because Citrix XenServer 5.0 mounts using software with non-default timeout values, use the values described in the Linux section Linux, page 33. To check or set Xen Citrix parameters, use the set_parm executable found in the /opt/hp/ directory. When executed, the options to change timeout values are displayed. NOTE: • The timeout values must be increased for Emulex single path (without multipath support) and QLogic single path being used in the environment. This is not only important for online upgrades but for general data integrity. • Online controller firmware upgrades are supported with Xen Citrix boot devices. Back up all storage system data Estimated time to complete: Varies When to perform: As close as possible to the upgrade Before beginning the upgrade, it is recommended that you perform a full verified backup of all storage system data. Although not required, it is always good practice to back up your data before performing major operations such as software upgrades. The backup should be scheduled as close to the upgrade process as possible. For more information about establishing and implementing good backup procedures for the EVA, contact your HP sales representative. TIP: If using server-based management, HP recommends that you also back up the management server before you begin the upgrade. Upgrading HP Command View EVA Follow the procedures in this section to upgrade HP Command View EVA on the management server. If you have an EVA4400 and are using array-based management, see Upgrading the management module for upgrade instructions. 36 Pre-upgrade tasks

NOTE:
For Microsoft Windows guests: set the windows SCSI timeout registry to 60secs, as follows:
1.
In the windows registry, find
HKEY_LOCAL_MACHINE\System\CurrentControlSet\
Services\Disk\TimeOutValue
2.
Set this value to 60 decimal (3Ch).
The ESX layer (VMFS, the VMware filesystem) controls timeouts of VMFS I/O. These values may vary
from ESX release to release.
Xen Citrix
For Xen Citrix, except for NFS SR timeouts, because Citrix XenServer 5.0 mounts using software with
non-default timeout values, use the values described in the Linux section
Linux
, page 33.
To check or set Xen Citrix parameters, use the
set_parm
executable found in the
/opt/hp/
<driver-specific>
directory. When executed, the options to change timeout values are displayed.
NOTE:
•
The timeout values must be increased for Emulex single path (without multipath support) and
QLogic single path being used in the environment. This is not only important for online upgrades
but for general data integrity.
•
Online controller firmware upgrades are supported with Xen Citrix boot devices.
