The datastore status is Mounted for some ESXi hosts but for other ESXi hosts the status is Mounted (but greyed out). I took putty session and found that partition table is fine and on executing
"~ # esxcfg-scsidevs -m | grep <Datastorename>" gives output as:
eui.00173800ef520028:1 :1 524t6f62-dfcf62a4-73f1-00215a9c0716 0 VM126datatore
-Unable to unmount datastore and it failed with error: "The Operation not allowed in current state"
Error Stack: Call "HostStorageSystem.UnmontVmfsVolume"
Datastore is in maintenance mode part of SDRS cluster. Refresh and Rescan also did not help.
