SRDF/Metro with HYPERMAX OS 5977.811.784 supports booting directly from a SAN environment. With this release, boot drives may be configured on SRDF/Metro devices to support highly availability across SRDF/Metro sites.
See Host support matrix example for additional information regarding specific operating systems and multipathing software supported.
Users should use the HBA BIOS (offline) or the HBA Management Utility (online) to configure the SAN-based boot devices. The BIOS or HBA management utility allows the user to specify primary and secondary paths for the boot drives. R1 side paths can be configured as the primary boot path and R2 side path as the secondary boot path. This will ensure reboots are seamless even when one of the sides is not available due to an outage.
See the following support documentation when configuring boot devices within an SRDF/Metro solution:
