Quick one here. Create a new logical disk via RAID5, after an old logical unit failed from only a single bad disk.<\/p>\n

No issues deleting the old logical disk, and creating a new one via HP storage controller commands.<\/a><\/p>\n

However was greeted with this nice error.<\/p>\n

I had the same problem and in order to fix it I had to run three commands through an SSH connection. From what I have seen and found this error comes from having disks that were part of different arrays and contain some data on them. When I ran the commands I was then able to connect the data stores with no issues.<\/p>\n

1. Show connected disks.<\/p>\n

ls -lha \/vmfs\/devices\/disks\/<\/p>\n

(Verify the disk is seen. You will probably see your disk ID then :1. This is a partition on the disk. We only need to work about the main disk ID.)<\/p>\n

2. Show the error on disk.<\/p>\n

partedUtil getptbl \/vmfs\/devices\/disks\/(disk ID)<\/p>\n

(It will probably indicate that the GPT is located beyond the end of the disk.)<\/p>\n

3. Wipe disk and rewrite with a basic MSDOS partion.<\/p>\n

partedUtil setptbl \/vmfs\/devices\/disks\/(disk ID) msdos<\/p>\n

(The output from this should be similar to msdos and the next line will be o o o o)<\/p>\n

I hope this helps you out.”<\/p>\n
