Boot Devices

The SRX210 Services Gateway can boot from two devices:

Internal NAND flash (default; always present)

USB storage key (alternate)

Dual-Root Partitioning Scheme

The dual-root partitions allow the SRX210 Services Gateways to remain functional if there is file system corruption and facilitate easy recovery of the corrupted file system.

The dual-root partitioning scheme keeps the primary and backup JUNOS Software images in two independently bootable root partitions. If the primary root partition becomes corrupted, the system will be able to boot from the backup JUNOS Software image located in the other root partition and remain fully functional.

When the SRX210 Services Gateway powers up, it tries to boot the JUNOS Software from the default storage media. If the device fails to boot from the default storage media, it tries to boot from the alternate storage media. With the dual-root partitioning scheme, the SRX210 Services Gateway first tries to boot the JUNOS Software from the primary root partition and then from the backup root partition on the default storage media. If both primary and backup root partitions of a media fail to boot, then the device tries to boot from the next available type of storage media. The SRX210 Services Gateway remains fully functional even if it boots the JUNOS Software from the backup root partition of storage media.

NOTE: SRX210 Services Gateway that ship from the factory with JUNOS Software Release 10.0 is formatted with the dual-root partitioning scheme.

Existing SRX210 Services Gateways that are running JUNOS Software Release 9.6 or earlier use the single-root partitioning scheme.

While upgrading these devices to JUNOS Software Release 10.0, you can choose to format the storage media with dual-root partitions (strongly recommended) or retain the existing single-root partitioning.
