IP Appliance – Flash, Disk-based or Hybrid

IP Appliance – Flash, Disk-based or Hybrid

You can tell whether your IP Appliance is flash, disk-based or hybrid based on the mount points of the /var and /opt partitions:

• On Disk-based systems, both the /var and /opt partitions are mounted on the hard disk (wd0)
• On Flash-based (diskless) systems, the /var and /opt partitions are mounted on v9fs (a file system based in the RAM – loaded at startup)
• On Hybrid systems (the HDD is used for local logging) the /opt partition is mounted on v9fs and the /var partition is mounted on the optional hard disk (wd1), assuming the customer has previously enabled the optional HDD for local logging as per kb article 1350934)

Use the “df -k” CLI command to verify your configuration as shown in the examples below. These apply to IP390, IP560 and IP12XX.
