Hello all--I'm trying to troubleshoot an iSCSI boot from a UCS managed server. The UCSM, I believe, is telling me that it can reach the storage array, but the storage array is telling me that the server is not online. Right now, I'm stuck in the server OS's installation wizard bc the server can't find the iSCSI node.
adapter 1/1/1 (mcp):1# iscsi_get_config
vnic iSCSI Configuration:
dhcp status: false
IP Addr: 172.25.253.119
Subnet Mask: 255.255.255.0
Target Idx: 0
Prev State: ISCSI_TARGET_DISABLED
Target Error: ISCSI_TARGET_NO_ERROR
IP Addr: 172.25.253.100
Boot Lun: 0
Ping Stats: Success (12.599ms)
I've double and triple checked that my initiator and target IQNs and IP addresses are right. The iSCSI VLAN is native on the iSCSI-vnic, and the upstream switch can ping the storage array.
Any suggestions on what all else I need to explore to get this thing working would be greatly appreciated. Thank you in advance! MM
1. check LUN masking on the storage side - your initiators should be there.
2. see that your array sees the initiators logging into the array while you try to boot
The details depend on your array.
Also check your lun number on the storage controller side.
Based on your ucsm output, the lun is assigned #0, so make sure it's also assigned 0 on the storage side.
