Power-Cycling the storage system

Note: Do not issue verify_disk_array while the SP is powering up. You must

wait until the SP has completed the powerup cycle.

Solaris does not generally support the powering down of a storage

device while the Solaris server is running. There are, however,

occasions when we recommend power-cycling a storage system as part

of service. When power-cycling a storage system, it is important to

observe the following guidelines:

 If the system is booted from the storage system, the server must be

shut down before the storage system is powered down.

 If the system does not boot from the storage system, it is still

important to unmount any file systems on the storage system before

power-cycling the storage system.

 EMC recommends that you stop all I/O, including raw I/O, before

power-cycling the storage system. However, the system will not

panic if raw I/O occurs when the storage system is powered down.

If there is any attempt at I/O while the storage system is off or

while it is going through its boot sequence, the failover software

will attempt to fail over.
