Replacing a A6725A disk

[Andrew Moody_1]

Just wanted to double check, I've to replace a failing A6725A disk in my rp7410. I'm happy from an OS perspective that it's ready to come out, FREE PE = TOTAL PE doing a pvdisplay. However what I wanted to check was is this model hotpluggable or do I have to take the system down? Looking at disk specs A6727A is described as Hotpluggable, but A6725A isn't.

Anyone know?

Shalom,

If it has a handle on it its hot swapable. Non-hotswappable disks are usually internal and inaccessible without tools.

Hi Andrew,
definitely it's a HOTPluggable HDD. (A6725A-73GB HotPlug Ultra SCSI disk for rp74/84)

Cheers guys, now just to make sure I pull the duff one and not the one with the active root vg on it eh?

One of the best ways to identify a physical disk is to run dd on it and look for the busy light. Ten stop dd and see that the light goes out, something like this:

dd if=/dev/rdsk/cXtYdZ of=/dev/null

dd reads the raw disk (inefficiently since bs=512) and keeps the light on steady.

Thanks, I'll just get back to HP first and get them to send me a working disk, the one they sent is duff...
