Determining Service Tag Information

you contact us.
• The service tag label is visible on the front of the array, on the right bezel latch block.
Obtaining Component Diagnostics
You can collect diagnostic information for one or more members of a PS Series group through the Group
Manager GUI or the CLI. See the
Group Administration guide or the CLI Reference for more information.
Troubleshooting Array Startup Failure
If your system halts during startup, check if:
• The array fault LEDs are lit. See Front-Panel Features and Indicators on page 3 .
• There is a constant scraping or grinding sound when you access the hard drive. See Obtaining Technical Sup-
port and Customer Service on page 39 .

Troubleshooting Array Connections
