Issue Description
There is a new S5600T storage in site, get power after connecting the cable, there will these phenomena after 15 minutes:
1. The power light of controller enclosure is always twinkling, the entire IO interface light in back-end is normal and the hard disk enclosure light is normal.
2. We can’t enter the management interface, connect by serial port, it warns “system is not ready”.
Handling Process
1. Examine the SAS cable connection from controller enclosure to configuration hard disk enclosure (the hard disk enclosure with coffer disk), we find that it doesn’t use P0 cascading interface of controller enclosure. Modify the palace of cable, then connect the P0 cascading interface of A0 and B0 slot to PRI cascading interface of hard disk enclosure.
2. Reboot the device, then connect by serial port. All is normal.
Root Cause
Looking from phenomena, the storage hasn’t started up normally, but there is no alarm for hardware, so we doubt it’s the wrong connection of cascading cable, it leads the difference of DB information.
Suggestions
We should operate as instructor when networking in site.
