FC10 Hot Plug disk replacement


I have an N4000/FC10/HP-UX 11.00.
All the 10 disks in FC10 are HP 18.2GST318452FC.

Once of the disk in FC10 is giving a read/write error and hence I want to replace.
Only some blocks seems to be defective. SAM is showing the HDD as good.

I have unmounted the filesystem on this disk and also deactivated the volumegroup in the which the defective HDD is present.

It has been found that with the new HP 18.2GST318452FC disk it gives NO_HW in ioscan.

I have already tried with 4 new disk but the same issue. These 4 disks were earlier used with another FC10 with another N-Class.

What needs to be done?

Everything is possible

Re: FC10 Hot Plug disk replacement

As soon as you run 'ioscan' it should find newly installed disk. The one exception for FC disks is that new disk has another WWN. You need to use 'fcmsutil ... replace_dsk ...' to tell fcms driver that disk has been changed (see 'man fcmsutil')
