HMC Commands
| lshmc –n | (lists dynamic IP addresses served by HMC) |
| lssyscfg –r sys –F name,ipaddr | (lists managed system attributes) |
| lssysconn –r sys | (lists attributes of managed systems) |
| lssysconn –r all | (lists all known managed systems with attributes) |
| rmsysconn –o remove –ip | (ipaddr from lssysconn list (removes a managed system from the HMC) |
| mkvterm –m {msys} –p {lpar} | (opens a command line vterm from an ssh session) |
| rmvterm –m {msys} –p {lpar} | (closes an open vterm for a partition) |
Activate a partition
| chsysstate –m managedsysname –r lpar –o on –n partitionname –f profilename –b normal chsysstate –m managedsysname –r lpar –o on –n partitionname –f profilename –b sms |
Shutdown a partition
| chsysstate –m managedsysname –r lpar –o {shutdown/ossshutdown} –n partitionname [-immed][-restart] |
VIO Server Commands
| lsdev –virtual | (list all virtual devices on VIO server partitions) |
| lsmap –all | (lists mapping between physical and logical devices) |
| oem_setup_env | (change to OEM [AIX] environment on VIO server) |
Create Shared Ethernet Adapter (SEA) on VIO Server
| mkvdev –sea{physical adapt} –vadapter {virtual eth adapt} –default {dflt virtual adapt} –defaultid {dflt vlan ID} |
SEA Failover
| ent0 – GigE adapter | |
| ent1 – Virt Eth VLAN1 | (Defined with a priority in the partition profile) |
| ent2 – Virt Eth VLAN 99 | (Control) |
| mkvdev –sea ent0 –vadapter ent1 –default ent1 –defaultid 1 –attr ha_mode=auto ctl_chan=ent2 (Creates ent3 as the Shared Ethernet Adapter) |
|
Create Virtual Storage Device Mapping
| mkvdev –vdev {LV or hdisk} –vadapter {vhost adapt} –dev {virt dev name} |
Sharing a Single SAN LUN from Two VIO Servers to a Single VIO Client LPAR
| hdisk3 = SAN LUN | (on vioa server) |
| hdisk4 = SAN LUN | (on viob, same LUN as vioa) |
| chdev –dev hdisk3 –attr reserve_policy=no_reserve | (from vioa to prevent a reserve on the disk) |
| chdev –dev hdisk4 –attr reserve_policy=no_reserve | (from viob to prevent a reserve on the disk) |
| mkvdev –vdev hdisk3 –vadapter vhost0 –dev hdisk3_v | (from vioa) |
| mkvdev –vdev hdisk4 –vadapter vhost0 –dev hdisk4_v | (from viob) |
VIO Client would see a single LUN with two paths.
| lspath –l hdiskx | (where hdiskx is the newly discovered disk) |
| This will show two paths, one down vscsi0 and the other down vscsi1. |
