Understanding ML6000 drive lights
Looking for some help on this one...
We have a slew of WN444's (LTO4-FC drives) for our ML6000. The problem is that they are not accessible to the host. If I remove the lid and peek inside, none of the drives have any SCD errors. What is more perplexing is that the library can read all the VPD information (OCP shows serial, firmware, model #, etc.)
On the back of the drive, the blue status light (top right) stays solid and the green status light (bottom most light) blinks one a second. I'll try digging into more resources, but I'm truly stumped to why there are like 6 of them exactly like this.
Thanks!

Hello TapeDriveGuy,
When it comes to your tape drives the blue light Solid ON = Offline. Ready to be removed or replaced. So if you have replaced the drive then you should be able to go into the web utility or from the operator panel and put the drive back as an online status. Once the drive is online it should update the firmware if it needs to. Here is how to confirm that the drive is in an online status:
From the web client, select Operations>Drive>Change Mode>Offline>Apply.
From the operator panel, select Operations>Change Drive Mode>Offline>Apply.
The green light blinking once a second is normal operation & is what should be seen. If you put the drive online & it is still showing as having a solid Blue light then I would try to move the drive to another slot to see if you are getting the same error.
Please let us know if you have any other questions.
