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 ” Disconnecting external arrays or LUs ” on page 98 and ” Checking the connection status
and resuming external LU operations (Check Paths & Restore Vol.) ” on page 100 for 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 ” on page 98 for more information.
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.) ” on page 100 for 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.
