Example of PXE boot for ESXi on SeaMicro SM15000 server.

These instructions assume you have already set up a working netboot environment, complete with tftp server. What follows below is a doctored cobbler setup, so YMMV depending on how you manage your netboot environment. Note that running cobbler sync will clobber these files, so this is really just a temporary solution.

First, copy the contents of the ESXi 5.1 ISO to /var/lib/tftpboot/images/esxi5-x86_64. This should look something like the following for ESXi 5.1:

[vince@cobbler tftpboot]$ cd images/esxi5-x86_64/
[vince@cobbler esxi5-x86_64]$ ls
a.b00         boot.cfg      isolinux.cfg  net_enic.v00  safeboot.c32  scsi_fni.v00  scsi_rst.v00
ata_pata.v00  chardevs.b00  k.b00         net_forc.v00  sata_ahc.v00  scsi_hps.v00  s.v00
ata_pata.v01  efiboot.img   mboot.c32     net_igb.v00   sata_ata.v00  scsi_ips.v00  tboot.b00

Generating the commands needed to create pools, volumes and then assign them to 64 servers in a SeaMicro chassis.
#!/usr/bin/python
# SSDs in slots 0-1 of each S-card.
# HDDs in slots 2-7 of each S-card.
# Application A - 16 servers
# Assign one 64GB SSD volume to vdisk 0
# Assign three whole-disk volumes to each of vdisk 1, 2, 3
# Application B - 48 servers
# Assign one 32GB SSD volume to disk 0

Rename external storage so that JBOD disks are renamed in the form: jbod-S-D/d where S == S-card slot, D == JBOD internal device (0,1,2,3), d == disk number in the internal device.
#!/usr/bin/python
import re, sys
show_storage_external_brief = sys.stdin.readlines()
pattern = re.compile(r"^\s+(?P<name>\S+)\s+(?P<device>\S+)\s+(?P<slot>\d+)")
slots_seen = { }
# trying out what happens when we sort the JBOD WWNs
for line in sorted(show_storage_external_brief):
m = pattern.match( line )
