Very frequent disks failures in my EVA 4400
There are very frequent failures of disk drives in my EVA 4400. I don't know the reason why this is happening. At time 3 disks can fail simultaneously.Thank God that 99% of the failures are only happening among the UNGROUPED disks, but this is very surprising.
Please Advice.

Re: Very frequent disks failures in my EVA 4400
I have just upgraded the EVA controller firmware from 09522000.SSS to 09534000.SSS successfully, but just after that, 4 disks started showing amber light with FAIL status. The failed disks after the firmware upgrade include 2 previously failed ones that have been resat with green light and 2 new ones: All from the UNGROUP DISKS fortunately.
How can this behaviour be interpreted ?
The firmware revision of the disks is HP06.
Do you recommend a Firmware Upgrade for the disks ?
Please Advice.
Best Regards,
Yaboto

Re: Very frequent disks failures in my EVA 4400
In some cases it is necessary to do a full power-cycle.
In all cases it is necessary to verify that every disk drive enclosure's I/O module has accepted the new firmware.
> The firmware revision of the disks is HP06.
This doesn't mean much to me, sorry. There are different models sold, sometimes with the same, sometimes with a different revision number as 'current'.
But yes, please upgrade to the most recent bundle as suggested in the other thread:

Re: Very frequent disks failures in my EVA 4400
I have 23 grouped disks (default disk group) and 13 ungrouped disks.
I left some disks ungrouped as a way of managing the space allocation: we may need some disks in reserve to create a second disk group in the future.
Please what do you advice me ?

Re: Very frequent disks failures in my EVA 4400
It also gives you the most capacity, because with two disk groups you have two so-called "disk group protection levels" (they don't "protect" anything in the form of VRAID, but are the equivalent of virtualized spare disks).
