A Notes on connecting external arrays

NOTE:
If you have an EVA or MSA connected as external storage and you need to perform a firmware upgrade
on the EVA or MSA, you must use the EVA/MSA offline firmware upgrade function. When the EVA or
MSA is connected as XP external storage, online EVA/MSA firmware upgrade is not supported at this
time. Therefore, you must stop host I/O to the arrays in question, and issue the Disconnect Subsystem
command before the upgrade. After performing the upgrade, issue the Check Paths & Restore Vol.
command. See
Checking the connection status and resuming external LU operations (Check Paths & Restore Vol.)
details. You must also perform these procedures on other external arrays that do not support online firmware
upgrade
NOTE:
If your application server contains boot devices from external arrays that are EVA or MSA-resident, and
you need to perform a firmware upgrade on the EVA or MSA, you must shut down any servers that boot
from these arrays (through the XP, or otherwise) before the upgrade procedure. Perform the following
steps:
1. Power down the application server containing boot devices from the external array.
2. From XP Remote Web Console, issue the Disconnect Subsystem command. See
Disconnecting external arrays or LUs
3. Perform the external array firmware upgrade as directed in the external array's user documentation.
4. From XP Remote Web Console, issue the Check Paths & Restore Vol. command after the firmware
has been upgraded. See the
Checking the connection status and resuming external LU operations (Check Paths & Restore Vol.)
more information.
5. Power on the application server, and resume the applications.
If the boot device is from an external array that does not support online firmware upgrade, you also must
perform this procedures. See the firmware upgrade procedure for the external array for instructions.
