How to check why a UCS blade server can’t boot from san
UCS-LAB-A# connect adapter 1/4/1

- FLOGI State : flogi est (fc_id 0x910001)
- PLOGI Sessions
- WWNN 50:0a:09:81:88:dd:97:bf WWPN 50:0a:09:81:88:dd:97:bf fc_id 0x910003
- LUN's configured (SCSI Type, Version, Vendor, Serial No.)
LUN ID : 0x000a000000000000 (0x0, 0x4, NETAPP , P4DsRoviYRlA)
- REPORT LUNs Query Response
LUN ID : 0x0004000000000000
LUN ID : 0x000a000000000000
- Nameserver Query Response
- WWPN : 50:0a:09:81:88:dd:97:bf
You can see that:
- The vnic command shows Server’s vHBAs (7 & 8, one for each fabric)
- the configuration at the UCS is to boot from WWPN 50:0a:09:81:88:dd:97:bf, LUN 10 (0x10) (Marked yellow)
- The server has access to WWPN 50:0a:09:81:88:dd:97:bf, Luns 4 & 10 (Marked brown)
so Zonning (At the MDS) and Lun masking (At NetApp) are OK, and the server will Boot
