Storage Enclosure Issues And Restrictions - HP Smart Array 5300A User Manual

You will be presented with a choice of either recovering (making optimal)
these devices or leaving them in the failed state. There is no default option
under this scenario, and mandatory 'user intervention' is required.

Storage Enclosure Issues and Restrictions

•
Users are advised to follow the power sequencing rules below to avoid
possible array volume state changes affecting the availability of user data:
When removing power to a storage enclosure attached to a Smart Array
controller, first remove power to the host system, followed by powering off
the storage enclosure.
When powering a system on, ensure all storage enclosures attached to a Smart
Array controller first receive power before applying power to the host system.
•
The BA610-6D internal disk cages are only supported with Nile logic cards
P/N 3R-A1629-AA/010615-001 of rev. 0B. Cards with P/N 3R-A1629-
AA/010615-001 of rev. 0A are not supported with Smart Array 5300A
controllers. Customers who own BA610-6D modules with logic cards of P/N
3R-A1629-AA/010615-001 of rev. 0A and want to take advantage of internal
RAID must contact HP Field Service to have their 3R-A1629-AA/010615-001
rev. 0A cards replaced.
•
When configuring a Smart Array 5300A controller attached to a storage
enclosure configured with a dual bus I/O module, each of the enclosure's SCSI
bus segments may be attached to a Smart Array controller instance.
Connecting a controller or adapter other than another Smart Array controller
to the second SCSI bus segment of the enclosure is however unsupported.
•
If a Smart Array 5300A controller loses communication with a storage
enclosure, then all physical drives in this enclosure are seen via SNMP Agent
as located in an enclosure Bay 255. This typically means there is a hardware
problem with the enclosure. You should contact HP Services for the enclosure
troubleshooting.
