So at work, we needed to have some work performed on one of the SANs. To do the work we went ahead an powered our blade servers utilizing the SAN off. After the SAN was repaired (through means of a cold boot) 16 of our 32 BL25p blades refused to power on. There was no pattern to it, no single blade enclosure, no unique software. When you pressed the power button on the blades they just refused to turn on. It was more like they thought about turning on for a moment and then replied “Hell No.” Luckily we made due with some spares and reallocated blades from another similar setup elsewhere, but seriously how does this happen?
According to HP this is an issue that we should of fixed with upgrading iLO back in the spring. You gotta love quality engineering.
