hi,
we have some problems with a lun. each attemtpt to start a vm, which use this lun, ends with following exception:
Failed to open '/vmfs/volumes/4c5a5ebd-a904712c-0032-001517ce8e38/icg4aida/icg4aida-flat.vmdk' : Input/output error
or
Cannot open the disk '/vmfs/volumes/4c5a5ebd-a904712c-0032-001517ce8e38/icg4aida/temp.vmdk' or one of the snapshot disks it depends on.
is there a tool to check the lun and if yes repair it?
we tried to remove the lun and reattach it, but we can not remove it,because it is shown as busy.
there are also strange things when we want to view the storage in vcenter gui. in the vm we had the storage attached to (in the past) we can see it under the devices tab but not in the storage tab. On the other two servers we see the lun in both tabs.
we are using esxi4.1 on a intel modular server
hope you can follow my explainations and thanks in advance
