исправление статуса

 Сетевой диск требует 2 пути до него, если сетевуха одна, то можно пометить как локальный
<code bash><pre>
esxcli storage nmp satp rule add -s VMW_SATP_LOCAL --device diskid --option="enable_local"     (replace the diskid with the disk identifier)

esxcli storage core claiming reclaim -d diskid   (replace the diskid with the disk identifier)

esxcli storage core claimrule load

esxcli storage core claimrule run
