Troubleshooting Common Issues
This section identifies common issues for the Dell EqualLogic MEM. For troubleshooting issues related to importing EqualLogic storage to
PowerStore, see the Importing External Storage to PowerStore Guide.
Table 7. Troubleshooting the Dell EqualLogic MEM
Problem Possible Cause/Solution
Cannot install the MEM bundle
• The VIB was extracted before installation.
• The VIB was not first copied to the ESXi location.
iSCSI logins cannot be seen from any
vmknics
Did not bind vmknics to the iSCSI initiator. See iSCSI Network Configuration
Requirements.
iSCSI logins cannot be seen from all vmknics
• Volume access is not properly set for all vmknics to log in.
• If using IP ACLs, access must be granted to all VMkernel ports bound to the iSCSI
initiator.
• If using Broadcom iSCSI offload NICs and using IQN for volume access, an IQN entry
is required for each Broadcom iSCSI offload NIC that is bound to the iSCSI initiator.
Array limits of iSCSI sessions exceeded Session limits on ESXi server need to be lowered.
Logins from Broadcom NIC with iSCSI
offload cannot be seen
The Broadcom iSCSI offload supports jumbo frames in ESXi 5.1 and later, but not in ESXi
5.0 and earlier. If you are using ESXi 5.0 or earlier, for vmknic and vswitch, MTU must be
set to 1500.
Do not see the expected number of sessions
for Broadcom NIC with iSCSI offload
The values for the Broadcom session limits are documented in vSphere5.x Configuration
Maximums.
esxcli equallogic commands are not
recognized
The hostd agent was not restarted after the MEM installation.
Fewer iSCSI sessions created than expected This behavior is expected in the following cases:
• Your configuration is exceeding one of the three EHCM maximum settings
(TotalSessions, VolumeSessions, or MemberSessions). For example, if you
have a single-member pool, and MemberSessions is set to the default value of 2,
