Re: Predictive Disc Failure

thanks...

I ask because even though we have "five nines" against "Failure",
it appears when you consider the probability of needing to replace drives based on predictive failure, versus probability of a drive failing, that percentage is lower.
how much lower???

We have several SAN's (non-IBM), and even though they have hot-swap drives, there are times when we are waiting for a drive to show up on site while a drive is in a predictive failure state. in fact, we had
a SAN crash a couple of months ago because of this very situation...

The feature code for this is called "Hot Spare". You have to be VERY
large for IBM to even consider this. I have a customer with over 1,000
drives and they are NOT large enough.

Does IBM let you have a "spare" drive on site?

is there some feature code that allows this?

just "a wink" from your CE?

Thank you to those who weighed in on this .... the replacement unit
should be here on Monday and it will get installed. Just an investment
in some time, the disc itself is covered by our IBM maintenance
agreement.
