Single Drive Error [NSM 160, NSM 260] (6502)
Scenario
A drive may become unavailable, causing the RAID status to go Degraded or
Off, depending on the RAID configuration.
Workarounds
The following three options should be tried, in order. If one does not fix the
problem, try the next one.
• Reseat the drive using the instructions in the User Manual or the Online
Help. If the drive does not start rebuilding, and the drive status shows
Inactive in the Disk Setup tab, select the drive and click Add to RAID.
• Reboot the storage module. The drive comes online and begins rebuilding.
• Replace the drive and rebuild the array.
Network Management
Unable To Set Frame Size Or Flow Control On The VSA (8070)
Explanation
There are options in both the Centralized Management Console and the
Configuration Interface to modify the frame size and flow control network
parameters. These options are not currently supported by the VMware guest
OS network driver. Any changes made to these variables using either
interface will be accpted but no change to the physical network connection will
be made. Any changes required for performance or redundancy of the network
interface should be made in the ESX configuration using the VMware Virtual
Infrastructure Client Interface.
Flow Control Behavior Is Erratic On Bonded NICs (7575)
Scenario
The flow control on the NIC bond does not consistently affect the flow control
on either NIC interface. Modifying the flow control on the NIC bond produces
unpredictable results.
