If there is a certificate mismatch, trust issue, or certificate expiration, communication between vCenter and the IOFilter provider can fail, resulting in the VASA provider being reported as offline.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Impact<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">If the VASA Provider is offline, users may encounter the following issues:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"\">At the end of the failover or failback process, JetStream DR will attempt to attach the storage policy to the VM disks to resume protection. Even though VM data will be restored, if the VASA provider is offline, the storage policy attachment may fail. The affected VM will need to be re-protected after the VASA provider is restored to an online state.<\/li>\n\n\n\n<li class=\"\">Similarly, when protecting a new VM, the JetStream DR storage policy cannot be attached if the VM resides on an ESXi host where the VASA provider is offline. As a result, VM protection may fail until the VASA provider issue is resolved.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">AVS<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Create a Microsoft Support ticket from the location: <strong>Azure Portal \u2192 AVS Private Cloud<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Provide Microsoft Support with the <strong>FQDN of the affected ESXi host<\/strong> where the VASA provider is offline and request that they investigate and restore the VASA provider to an online state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the Microsoft Support team confirms that the issue has been resolved, perform the validation check described below.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">On-Premises<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Contact Broadcom Support and request that they perform necessary corrective actions to restore the VASA provider to an online state.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Broadcom provides detailed guidance for resolving this issue in the Knowledge Base article:<br><a href=\"https:\/\/knowledge.broadcom.com\/external\/article?legacyId=88159\">https:\/\/knowledge.broadcom.com\/external\/article?legacyId=88159<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After the Broadcom Support team confirms that the issue has been resolved, perform the validation check described below.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Validation Check<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After corrective actions have been performed by the support team, follow the below steps to validate proper system operation:<\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li class=\"\"><strong>Verify the VASA provider status in vCenter<\/strong>\n<ul class=\"wp-block-list\">\n<li class=\"\">Navigate to <strong>vCenter \u2192 Configure \u2192 Storage Providers<\/strong>.<\/li>\n\n\n\n<li class=\"\">Confirm that the IOFilter provider for the affected ESXi host reports an &#8220;Online&#8221; status.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li class=\"\"><strong>Verify the host status in JetStream DR plugin<\/strong>\n<ul class=\"wp-block-list\">\n<li class=\"\">Navigate to <strong>JetStream DR \u2192 Health View \u2192 Hosts<\/strong>.<\/li>\n\n\n\n<li class=\"\">Confirm that the affected host status is &#8220;OK.&#8221;<\/li>\n\n\n\n<li class=\"\">Verify that <em>&#8220;<\/em>VASA_PROVIDER_OFFLINE&#8221; is no longer reported.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li class=\"\"><strong>Validate VM protection<\/strong>\n<ul class=\"wp-block-list\">\n<li class=\"\">If VM protection failed previously because the VASA provider was offline, retry the protection operation after confirming that the VASA provider is online.<\/li>\n\n\n\n<li class=\"\">Confirm that the VM protection task successfully completes and the associated JetStream DR policy is attached to the VM disks.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li class=\"\"><strong>Validate failover\/failback operations<\/strong>\n<ul class=\"wp-block-list\">\n<li class=\"\">If attaching the JetStream DR storage policy failed during a previous operation, re-protect the affected VMs after confirming that the VASA provider is online.<br><\/li>\n<\/ul>\n<\/li>\n\n\n\n<li class=\"\"><strong>Confirm overall JetStream DR health<\/strong>\n<ul class=\"wp-block-list\">\n<li class=\"\">Verify that the affected host and associated VMs are in a healthy state in JetStream DR.<\/li>\n\n\n\n<li class=\"\">Confirm that there are no remaining &#8220;VASA_PROVIDER_OFFLINE&#8221; alerts or related storage-policy errors.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Once all the above checks have been successfully completed, JetStream DR software can be considered to be operating nominally with respect to VASA.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Problem The vSphere APIs for Storage Awareness (VASA) provider is offline preventing proper operation of JetStream DR software.
