Issue with cache cluster.

Resolution

• Run the following command:

Remove-SPDistributedCacheServiceInstance

$SPFarm = Get-SPFarm

$cacheClusterName = "SPDistributedCacheCluster_" + $SPFarm.Id.ToString()

$cacheClusterManager = [Microsoft.SharePoint.DistributedCaching.Utilities.SPDistributedCacheClusterInfoManager]::Local

$cacheClusterInfo = $cacheClusterManager.GetSPDistributedCacheClusterInfo($cacheClusterName);

$instanceName ="SPDistributedCacheService Name=AppFabricCachingService"

$serviceInstance = Get-SPServiceInstance | ? {($_.Service.Tostring()) -eq $instanceName -and ($_.Server.Name) -eq $env:computername}

if([System.String]::IsNullOrEmpty($cacheClusterInfo.CacheHostsInfoCollection))

{

$serviceInstance.Delete()

}

• After this we ran following command

$SPFarm = Get-SPFarm

$cacheClusterName = "SPDistributedCacheCluster_" + $SPFarm.Id.ToString()

$cacheClusterManager = [Microsoft.SharePoint.DistributedCaching.Utilities.SPDistributedCacheClusterInfoManager]::Local

$cacheClusterInfo = $cacheClusterManager.GetSPDistributedCacheClusterInfo($cacheClusterName);

$instanceName ="SPDistributedCacheService Name=AppFabricCachingService"

$serviceInstance = Get-SPServiceInstance | ? {($_.Service.Tostring()) -eq $instanceName -and ($_.Server.Name) -eq $env:computername}

if([System.String]::IsNullOrEmpty($cacheClusterInfo.CacheHostsInfoCollection))

{

Add-SPDistributedCacheServiceInstance

$cacheClusterInfo.CacheHostsInfoCollection

}

ran Get-CacheHost and it shows the service is up
