Problem
Following the power-on activity of the Storage shelf (or shelves) and the two compute nodes in an Access 3340 cluster, storage services such as Deduplication for Long Term Retention (MSDP/LTR) may not start automatically.
Error Message
There is no error shown, but services that should start after powering on the appliance may need to be manually started from the Access Web UI or Management CLISH.
The service may show OFFLINE after the initial boot
access_clus> support services showall
Service access-n1 access-n2

dedupe OFFLINE OFFLINE
Cause
In some circumstances, the storage/disks may not be fully initialized after powering on the storage shelf/shelves.
The Access 3340 hardware installation guide states that waits for two to three minutes before powering on the server nodes, but this may not be enough time for the disks/RAID to be ready.
Turning on the hardware and verifying operation
Wait 2 minutes or 3 minutes for the shelf to initialize. The shelf is quieter when it has initialized.
Solution
Please allow the storage shelf more time to initialize prior to powering on the cluster nodes.
10 minutes will be enough time for the shelf/shelves to fully spin up and the RAID volumes to initialize.
Otherwise, individual services can be started manually after boot if required:
ex.
access_clus> dedupe status
Hostname Status
=========== =======
access-n1 OFFLINE
access-n2 OFFLINE
access_clus> dedupe start
access_clus> dedupe status
Hostname Status
=========== =======
access-n1 ONLINE
access-n2 OFFLINE
