2nd Datastore missing after physical Harddisk failure

[Seanbb]

Dear all, Need some advise for the following;

ESX4.1

One of the physical harddisk is spoilt on 2nd partition (red light)

Replaced with hot swap

Using 2 Partition, 3 disks raid 5, 5 disks raid 5

2 datastores, however after replaced to the new harddisk, 2nd datastore is missing, 1st datastore still working

One of the VMs not able to start up  (had 2 vm disk attached, 1st disk on datastore1, 2nd disk on datastore2)

Possible to advise should I add storage and add back the 2nd datastore? I worried that it will format the data to become empty disk. Any other possible solution to add back the 2nd datastore with the data inside and turn on my VM?

Appreciate

Welcome to the Community,

if this is a hot-swap capable controller and you are using hot-swappable disks, then this seems to be a serious issue with the controller or its firmware!? Anyway, please run fdisk -lu from the ESXi host's command line and post the output.

Partition table entries are not in disk order

[a_p_]

The output shows only one of the two disks/volumes (the installation disk with the ESXi partitions and the first VMFS datastore)!? Please check the RAID configuration (e.g. in the controller's BIOS) to see whether the second RAID shows any issues.
