How to proactively replace a disk on VNX5800
Hi,
We've requested a replacement to proactively replace a failing disk on VNX5800. It looks like we can't do it. Copytohotspare and replace are both disabled with the menu as the screenshot. Can someone please advise how to. Many thanks.

Cool ! Seems that the command has changed for VNX2.
it's now "copytodisk sourcedisk destdisk"
you'll need to note the address of your spare, and enter into the cmd.
naviseccli -h arrayspaddress copytodisk 2_2_5 x_x_x

Thanks for your quick reply. But I've tried that command line before. It didn't work for me.
C:\Users\bliu>naviseccli -h 10.53.**.** -User bliu -Password **** -Scope 0 copytohotspare 2_5_5 -initiate
Error: copytohotspare command failed
Command not Supported
This command is not supported on this subsystem type.

Hi Brian,
VNX/2 with mixed RAID pools prevents initiating a proactive copy from the GUI. (As well as some other conditions)
From navisecCLI;
naviseccli -h arrayspaddress copytohotspare 2_5_5 -initiate
Note depending on your auth setup, you may need to add a -user -pass and -scope options.
Check status;
naviseccli -h arrayspaddress getdisk 2_5_5 -state -rb
....or check the disk icon in Unisphere which will have the "T" for transitioning. When complete, the disk will show as removed.

Makes sense since with MCR you no longer define hotspares – every unused disk can be used as a spare
So a copytohotspare command wouldn’t be correct
