LEDS FLASHING

Hello!

I have a storage with this caracteristics:
MSA500 G2 with 2 controllers (for redundancy)
10 x 146GB disks (14 slots in total)
MSA500 G2 4-port IO Module
Power: 735V (max)

Somethimes the leds in the disks starting to flashing...

I look for in the user guide and i found:

(when the 3 leds are flashing):
Do not remove the drive. Removing a drive may cause data loss in non-fault-tolerant configurations.

Either (1) the drive is part of an array being selected by an array configuration utility; (2) Drive Identification has been selected in
HP SIM; or (3) drive firmware is being updated.

When i use the array configuration utility the leds flashing but last week almost every day the leds are flashing...and i didn't use this...

Anyone knows why? Can it be a problem?

Re: LEDS FLASHING

Hi,
according to the:
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00182750/c00182750.pdf?jumpid=reg_R1002_USEN
a) the HDD drive leds are flashing when:
there is a high activity on the drive, or the drive is being configured as a part of array
b) they are not flashing when:
there is no activity on the drives

if you want to verify if everything is ok,
that check the LED nr 15, which is a drive failure LED:
a) if its green, then the array configured drive has failed,
b) if its off, then no drives has failed
the pain is one part of the reality

Hi,
this is an ERRATA of my reply, in the sentence "if you want to verify if everything is ok,
that check the (CONTROLLER - this was missing) LED nr 15, which is a drive failure LED:
a) if its green, then the array configured drive has failed,
b) if its off, then no drives has failed
