ODA hang/crash due to software raid-check

Hi,

Has anyone seen an official not for the scheduled 1am raid check causing a full system hang?

We had  an issue over the weekend that matches an unofficial document - details below.

If the ODA is having some load during raid-check, it can happen that the server freezes. Only IP layer seems to still be alive : server is replying to the ping command, but ssh layer is not available any more.
Nothing can be done with the ODA : no ssh connection, all logs and writes on the server are stuck, ILOM serial connection is impossible.

The only solution is to power cycle the ODA through ILOM.

Howdy, Stranger!
