Symmetrix-specific cautions and restrictions

Configuring a Boot Device on an EMC Storage Array

Cautions and restrictions for booting from EMC storage array

!CAUTION

If Linux loses connectivity long enough, the disks disappear from the system. To prevent further data from being lost in a situation like this, EMC recommends that the error behavior be changed from continue to remount read-only. To make this change, consult the manpage for tune2fs. A hard reboot is required to bring the system back to a usable state.

!CAUTION

You should configure the host with enough memory to eliminate the need for a swap partition. EMC cannot recommend an amount of memory as this varies greatly depending upon the environment.

EMC recommends shutting down the host server during any maintenance procedures that could make the boot disk unavailable to the host. Any of these events could crash a system booting from an EMC storage array.
