Symptoms
Occasionally, a LUN created on the Sun StorEdge [TM] 5210/5310 NAS array indicates "no partition table". This can be seen via the telnet menu interface or the Web Admin GUI.
example:

SE5310a                StorEdge 5310 NAS Disks & Volumes

  Drive       Volume(s)                                     Available
A. ide1d1      /cvol /dvol                                        0B
B. isp2d020    /home                                         398.6GB
C. isp4d001    /vol1                                         407.7GB
D. isp2d022    -- no partition table

Any attempts to configure this LUN by initializing it could be met with a failure, indicated by a message, "Invalid/Missing partition".

the problem can also be seen while trying to configure LUN paths using the telnet menu interface or the Web Admin GUI.

SE5310a                StorEdge 5310 NAS Configure Lun Path

Lun (Dasd_id 0xA00)                                     Primary Path Index
isp2d022  -- no partition table                                  1

Paths:
1. isp2d022  HBA 0x2, SID0x2, Lun 0x2  Up

All LEDs, front and back on the array could be green and there could be no indication of any errors on the NAS Recovery Manager(NRM) using the "Recovery Guru" functionality.

Resolution
Reboot the NAS head.
Once it has rebooted, perform the following actions.
1. If this is a cluster, then check the lun ownerships.
Make sure that the lun has been given an ownership.

In the telnet menu,
Under the menu "extensions" locate the option for FAILOVER/MOVE LUNS and
select it. (the corresponding letter changes depending on which features are enabled)

A similar screen will be seen:

SE5310-NASb StorageTek 5310C NAS Failover / move LUNs

      Failover Enabled Yes
Link Failover Enabled Yes
Link Down Timeout     60
Link Restore Timeout  60

   1) Current Raid Configuration
Adapter LUNS_Owned
isp2d021

   2) (NEW) Restore Raid Configuration
Adapter LUNS_Owned
isp2d021

      ENTER to move through fields    Save changes after last field
+------------------------------------------------------------------------+
|                                                                        |
|    1. Restore  2. Modify Lun Owner  3. Edit Failover  0. Cancel        |
|                                                                        |
+------------------------------------------------------------------------+

Make sure that the lun has been assigned an owner.

2. If that is indeed the case or if this is not a cluster, then using the following action, initialize the partition.

     D. Disks & Volumes
----> Enter the alphabet of the LUN to be configured.
-----> Enter "1" to initialize the LUN.

     Lun is initialized successfully.

Through the telnet menu, the LUN is seen as follows:

SE5310a                 StorEdge 5310 NAS Configure Disk

Through the Web Admin GUI, the LUN is seen to be "clean".

     LUN paths can also be configured successfully.
