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 offl ine 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 and Checking the connection status and resuming
external LU operations (Check Paths & Restore Vol.) 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 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.) for more information.
5.
Power on the application server, and resume the applications.
