If you use multipathing, you need to edit the timeout value in the iSCSI configuration file.
Step
- Edit the following file to provide the correct timeout value for your Host Utilities environment (DM-Multipath or Veritas Storage Foundation):
If you are using... |
Enter the following values... |
Red Hat Enterprise Linux 7 series, 6 series, or 5 series, SUSE Linux Enterprise Server 10, 11, or 12 series, SUSE Linux Enterprise Server KVM and XEN, and Red Hat Enterprise Linux KVM. |
Edit /etc/iscsi/iscsid.conf to include the following value:
- DM-Multipath environments: node.session.timeo.replacement_timeout = 5
- Veritas Storage Foundation environments: node.session.timeo.replacement_timeout = 120
|
Oracle VM 3 series |
Edit /etc/iscsi/iscsid.conf to include the following value:
node.session.timeo.replacement_timeout = 5 |
Red Hat Enterprise Linux 4 series |
Edit /etc/iscsi.conf to include the following DM-Multipath value:
- Remove the comment indicator from the ConnFailTimeout line in the Session Timeout Settings section.
- Set the value of ConnFailTimeout to 5
|
Citrix XenServer 6 series |
For existing Storage Repositories: - Edit /etc/iscsi/iscsid.conf to include the following value for DM-Multipath environments: node.session.timeo.replacement_timeout = 5
- Detach and then reattach SRs from XenCenter or by using the XenServer xe CLI.
This will reflect the new iSCSI timeout settings for the existing SRs.
For new Storage Repositories:- Edit /etc/iscsi/iscsid.conf to include the following value for DM-Multipath environments: node.session.timeo.replacement_timeout = 5
- Create the new SR.
New as well as existing SRs will be updated with the new iSCSI timeout settings.
|
Red Hat Enterprise Virtualization Hypervisor 6.2 and later |
- Edit /etc/iscsi/iscsid.conf to include the following value for DM-Multipath environments: node.session.timeo.replacement_timeout = 5
- Make sure that your iscsid.conf file is persistent across reboots: persist /etc/iscsi/iscsid.conf
